Blues is the name given to both a musical form and a music genre^[1] that originated in African-American communities of primarily the "Deep South" of the United States around the end of the 19th century from spirituals, work songs, field hollers, shouts and chants, and rhymed simple narrative ballads.^[2] The blues form, ubiquitous in jazz, rhythm and blues, and rock and roll is characterized by specific chord progressions, of which the twelve-bar blues chord progression is the most common. The blue notes that, for expressive purposes are sung or played flattened or gradually bent (minor 3rd to major 3rd) in relation to the pitch of the major scale, are also an important part of the sound.

The blues genre is based on the blues form but possesses other characteristics such as specific lyrics, bass lines and instruments. Blues can be subdivided into several subgenres ranging from country to urban blues that were more or less popular during different periods of the 20th century. Best known are the Delta, Piedmont, Jump and Chicago blues styles. World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience, especially white listeners. In the 1960s and 1970s, a hybrid form called blues-rock evolved.

The term "the blues" refers to the "blue devils", meaning melancholy and sadness; an early use of the term in this sense is found in George Colman's one-act farce Blue Devils (1798).^[3]Though the use of the phrase in African-American music may be older, it has been attested to since 1912, when Hart Wand's "Dallas Blues" became the first copyrighted blues composition.^[4][5]In lyrics the phrase is often used to describe a depressed mood.^[6]

Form[link]

The blues form is a cyclic musical form in which a repeating progression of chords mirrors the call and response scheme commonly found in African and African-American music. During the first decades of the 20th century blues music was not clearly defined in terms of a particular chord progression.^[7] With the popularity of early performers, such as Bessie Smith, use of the twelve-bar blues spread across the music industry during the 1920s and 30s.^[8] Other chord progressions, such as 8-bar forms, are still considered blues; examples include "How Long Blues", "Trouble in Mind", and Big Bill Broonzy's "Key to the Highway". There are also 16-bar blues, as in Ray Charles's instrumental "Sweet 16 Bars" and in Herbie Hancock's "Watermelon Man". Idiosyncratic numbers of bars are also encountered occasionally, as with the 9-bar progression in "Sitting on Top of the World" by Walter Vinson.

The basic 12-bar lyric framework of a blues composition is reflected by a standard harmonic progression of 12 bars in a 4/4 time signature. The blues chords associated to a twelve-bar blues are typically a set of three different chords played over a 12-bar scheme. They are labeled by Roman numbers referring to the degrees of the progression. For instance, for a blues in the key of C, C is the tonic chord (I) and F is the subdominant (IV).

The last chord is the dominant (V) turnaround, marking the transition to the beginning of the next progression. The lyrics generally end on the last beat of the tenth bar or the first beat of the 11th bar, and the final two bars are given to the instrumentalist as a break; the harmony of this two-bar break, the turnaround, can be extremely complex, sometimes consisting of single notes that defy analysis in terms of chords.

Much of the time, some or all of these chords are played in the harmonic seventh (7th) form. The use of the harmonic seventh interval is characteristic of blues and is popularly called the "blues seven".^[9] Blues seven chords add to the harmonic chord a note with a frequency in a 7:4 ratio to the fundamental note. At a 7:4 ratio, it is not close to any interval on the conventional Western diatonic scale.^[10] For convenience or by necessity it is often approximated by a minor seventh interval or a dominant seventh chord.

In melody, blues is distinguished by the use of the flattened third, fifth and seventh of the associated major scale.^[11] These specialized notes are called the blue or bent notes. These scale tones may replace the natural scale tones, or they may be added to the scale, as in the case of the minor blues scale, in which the flattened third replaces the natural third, the flattened seventh replaces the natural seventh and the flattened fifth is added between the natural fourth and natural fifth. While the 12-bar harmonic progression had been intermittently used for centuries, the revolutionary aspect of blues was the frequent use of the flattened third, flattened seventh, and even flattened fifth in the melody, together with crushing—playing directly adjacent notes at the same time (i.e., minor second)—and sliding, similar to using grace notes.^[12] The blue notes allow for key moments of expression during the cadences, melodies, and embellishments of the blues.

Blues shuffles or walking bass reinforce the trance-like rhythm and call-and-response, and they form a repetitive effect called a groove. Characteristic of the blues since its Afro-American origins, the shuffles played a central role in swing music.^[13] The simplest shuffles, which were the clearest signature of the R&B wave that started in the mid 1940s,^[14] were a three-note riff on the bass strings of the guitar. When this riff was played over the bass and the drums, the groove "feel" was created. Shuffle rhythm is often vocalized as "dow, da dow, da dow, da" or "dump, da dump, da dump, da":^[15] it consists of uneven, or "swung," eighth notes. On a guitar this may be played as a simple steady bass or it may add to that stepwise quarter note motion from the fifth to the sixth of the chord and back. An example is provided by the following guitar tablature for the first four bars of a blues progression in E:^[16][17]

Lyrics[link]

The lyrics of early traditional blues verses probably often consisted of a single line repeated four times; it was only in the first decades of the 20th century that the most common current structure became standard: the so-called AAB pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars.^[18] Two of the first published blues songs, "Dallas Blues" (1912) and "St. Louis Blues" (1914), were 12-bar blues featuring the AAB structure. W. C. Handy wrote that he adopted this convention to avoid the monotony of lines repeated three times.^[19]

The lines are often sung following a pattern closer to a rhythmic talk than to a melody. Early blues frequently took the form of a loose narrative. The singer voiced his or her "personal woes in a world of harsh reality: a lost love, the cruelty of police officers, oppression at the hands of white folk, [and] hard times."^[20] This melancholy has led to the suggestion of an Igbo origin for blues because of the reputation the Igbo had throughout plantations in the Americas for their melancholic music and outlook to life when they were enslaved.^[21][22]

The lyrics often relate troubles experienced within African American society. For instance Blind Lemon Jefferson's "Rising High Water Blues" (1927) tells about the Great Mississippi Flood of 1927:

"Backwater rising, Southern peoples can't make no time

I said, backwater rising, Southern peoples can't make no time

And I can't get no hearing from that Memphis girl of mine."

However, although the blues gained an association with misery and oppression, the lyrics could also be humorous and raunchy as well:^[23]

"Rebecca, Rebecca, get your big legs off of me,

Rebecca, Rebecca, get your big legs off of me,

It may be sending you baby, but it's worrying the hell out of me."

From Big Joe Turner's "Rebecca", a compilation of traditional blues lyrics

Hokum blues celebrated both comedic lyrical content and a boisterous, farcical performance style.^[24] Tampa Red's classic "Tight Like That" (1928) is a sly wordplay with the double meaning of being "tight" with someone coupled with a more salacious physical familiarity. Explicit contents led to blues sometimes being called dirty blues. Lyrical content of music became slightly simpler in post war-blues which focused almost exclusively on relationship woes or sexual worries. Many lyrical themes that frequently appeared in pre-war blues such as economic depression, farming, devils, gambling, magic, floods and dry periods were less common in post-war blues.^[25]

Author Ed Morales has claimed that Yoruba mythology played a part in early blues, citing Robert Johnson's "Cross Road Blues" as a "thinly veiled reference to Eleggua, the orisha in charge of the crossroads".^[26] However, the Christian influence was far more obvious.^[27] Many seminal blues artists such as Charley Patton or Skip James had several religious songs or spirituals in their repertoires.^[28] Reverend Gary Davis^[29] and Blind Willie Johnson^[30] are examples of artists often categorized as blues musicians for their music, although their lyrics clearly belong to the spirituals.

Origins[link]

The first publication of blues sheet music was Hart Wand's "Dallas Blues" in 1912; W. C. Handy's "The Memphis Blues" followed in the same year. The first recording by an African American singer was Mamie Smith's 1920 rendition of Perry Bradford's "Crazy Blues". But the origins of the blues date back to some decades earlier, probably around 1890.^[31] They are very poorly documented, due in part to racial discrimination within American society, including academic circles,^[32] and to the low literacy rate of the rural African American community at the time.^[33]

Chroniclers began to report about blues music in Southern Texas and Deep South at the dawn of the 20th century. In particular, Charles Peabody mentioned the appearance of blues music at Clarksdale, Mississippi and Gate Thomas reported very similar songs in southern Texas around 1901–1902. These observations coincide more or less with the remembrance of Jelly Roll Morton, who declared having heard blues for the first time in New Orleans in 1902; Ma Rainey, who remembered her first blues experience the same year in Missouri; and W.C. Handy, who first heard the blues in Tutwiler, Mississippi in 1903. The first extensive research in the field was performed by Howard W. Odum, who published a large anthology of folk songs in the counties of Lafayette, Mississippi and Newton, Georgia between 1905 and 1908.^[34] The first non-commercial recordings of blues music, termed "proto-blues" by Paul Oliver, were made by Odum at the very beginning of the 20th century for research purposes. They are now utterly lost.^[35]

Other recordings that are still available were made in 1924 by Lawrence Gellert. Later, several recordings were made by Robert W. Gordon, who became head of the Archive of American Folk Songs of the Library of Congress. Gordon's successor at the Library was John Lomax. In the 1930s, together with his son Alan, Lomax made a large number of non-commercial blues recordings that testify to the huge variety of proto-blues styles, such as field hollers and ring shouts.^[36] A record of blues music as it existed before the 1920s is also given by the recordings of artists such as Lead Belly^[37] or Henry Thomas^[38] who both performed archaic blues music. All these sources show the existence of many different structures distinct from the twelve-, eight-, or sixteen-bar.^[39][40]

John Lomax, pioneering musicologist and folklorist.

The social and economic reasons for the appearance of the blues are not fully known.^[41] The first appearance of the blues is often dated after the Emancipation Act of 1863,^[32] between 1870 and 1900, a period that coincides with Emancipation and, later, the development of juke joints as places where Blacks went to listen to music, dance, or gamble after a hard day's work.^[42] This period corresponds to the transition from slavery to sharecropping, small-scale agricultural production, and the expansion of railroads in the southern United States. Several scholars characterize the early 1900s development of blues music as a move from group performances to a more individualized style. They argue that the development of the blues is associated with the newly acquired freedom of the enslaved people.^[43]

According to Lawrence Levine, "there was a direct relationship between the national ideological emphasis upon the individual, the popularity of Booker T. Washington's teachings, and the rise of the blues." Levine states that "psychologically, socially, and economically, African-Americans were being acculturated in a way that would have been impossible during slavery, and it is hardly surprising that their secular music reflected this as much as their religious music did."^[43]

There are few characteristics common to all blues music, because the genre took its shape from the idiosyncrasies of individual performances.^[44] However, there are some characteristics that were present long before the creation of the modern blues. Call-and-response shouts were an early form of blues-like music; they were a "functional expression ... style without accompaniment or harmony and unbounded by the formality of any particular musical structure."^[45] A form of this pre-blues was heard in slave ring shouts and field hollers, expanded into "simple solo songs laden with emotional content".^[46]

Blues has evolved from the unaccompanied vocal music and oral traditions of slaves imported from West Africa and rural blacks into a wide variety of styles and subgenres, with regional variations across the United States. Though blues, as it is now known, can be seen as a musical style based on both European harmonic structure and the African call-and-response tradition, transformed into an interplay of voice and guitar,^[47][48] the blues form itself bears no resemblance to the melodic styles of the West African griots, and the influences are faint and tenuous.^[49][50]

In particular, no specific African musical form can be identified as the single direct ancestor of the blues.^[51] However many blues elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa. That blue notes pre-date their use in blues and have an African origin is attested by English composer Samuel Coleridge-Taylor's "A Negro Love Song", from his The African Suite for Piano composed in 1898, which contains blue third and seventh notes.^[52]

The Diddley bow (a homemade one-stringed instrument found in parts of the American South in the early twentieth century) and the banjo are African-derived instruments that may have helped in the transfer of African performance techniques into the early blues instrumental vocabulary.^[53] The banjo seems to be directly imported from western African music. It is similar to the musical instrument that griots and other Africans such as the Igbo^[54] played (called halam or akonting by African peoples such as the Wolof, Fula and Mandinka).^[55] However, in the 1920s, when country blues began to be recorded, the use of the banjo in blues music was quite marginal and limited to individuals such as Papa Charlie Jackson and later Gus Cannon.^[56]

Blues music also adopted elements from the "Ethiopian airs", minstrel shows and Negro spirituals, including instrumental and harmonic accompaniment.^[57] The style also was closely related to ragtime, which developed at about the same time, though the blues better preserved "the original melodic patterns of African music".^[58]

The musical forms and styles that are now considered the "blues" as well as modern "country music" arose in the same regions during the 19th century in the southern United States. Recorded blues and country can be found from as far back as the 1920s, when the popular record industry developed and created marketing categories called "race music" and "hillbilly music" to sell music by blacks for blacks and by whites for whites, respectively. At the time, there was no clear musical division between "blues" and "country," except for the ethnicity of the performer, and even that was sometimes documented incorrectly by record companies.^[59][60]

Though musicologists can now attempt to define “the blues” narrowly in terms of certain chord structures and lyric strategies thought to have originated in West Africa, audiences originally heard the music in a far more general way: it was simply the music of the rural south, notably the Mississippi Delta. Black and white musicians shared the same repertoire and thought of themselves as “songsters” rather than “blues musicians.” The notion of blues as a separate genre arose during the black migration from the countryside to urban areas in the 1920s and the simultaneous development of the recording industry. “Blues” became a code word for a record designed to sell to black listeners.^[61]

The origins of the blues are closely related to the religious music of the Afro-American community, the spirituals. The origins of spirituals go back much further than the blues, usually dating back to the middle of the 18th century, when the slaves were Christianized and began to sing and play Christian hymns, in particular those of Isaac Watts, which were very popular.^[62] Before the blues gained its formal definition in terms of chord progressions, it was defined as the secular counterpart of the spirituals. It was the low-down music played by the rural Blacks.^[63]

Depending on the religious community a musician belonged to, it was more or less considered as a sin to play this low-down music: blues was the devil's music. Musicians were therefore segregated into two categories: gospel and blues singers, guitar preachers and songsters. However, at the time rural Black music began to get recorded in the 1920s, both categories of musicians used very similar techniques: call-and-response patterns, blue notes, and slide guitars. Gospel music was nevertheless using musical forms that were compatible with Christian hymns and therefore less marked by the blues form than its secular counterpart.^[63]

Pre-war blues[link]

The American sheet music publishing industry produced a great deal of ragtime music. By 1912, the sheet music industry had published three popular blues-like compositions, precipitating the Tin Pan Alley adoption of blues elements: "Baby Seals' Blues" by "Baby" F. Seals (arranged by Artie Matthews), "Dallas Blues" by Hart Wand and "The Memphis Blues" by W. C. Handy.^[64]

Sheet music from "St. Louis Blues" (1914)

Handy was a formally trained musician, composer and arranger who helped to popularize the blues by transcribing and orchestrating blues in an almost symphonic style, with bands and singers. He became a popular and prolific composer, and billed himself as the "Father of the Blues"; however, his compositions can be described as a fusion of blues with ragtime and jazz, a merger facilitated using the Cuban habanera rhythm that had long been a part of ragtime;^[26][65] Handy's signature work was the "St. Louis Blues".

In the 1920s, the blues became a major element of African American and American popular music, reaching white audiences via Handy's arrangements and the classic female blues performers. The blues evolved from informal performances in bars to entertainment in theaters. Blues performances were organized by the Theater Owners Bookers Association in nightclubs such as the Cotton Club and juke joints such as the bars along Beale Street in Memphis. Several record companies, such as the American Record Corporation, Okeh Records, and Paramount Records, began to record African American music.

As the recording industry grew, country blues performers like Bo Carter, Jimmie Rodgers (country singer), Blind Lemon Jefferson, Lonnie Johnson, Tampa Red and Blind Blake became more popular in the African American community. Kentucky-born Sylvester Weaver was in 1923 the first to record the slide guitar style, in which a guitar is fretted with a knife blade or the sawed-off neck of a bottle.^[66] The slide guitar became an important part of the Delta blues.^[67] The first blues recordings from the 1920s are categorized as a traditional, rural country blues and a more polished 'city' or urban blues.

Country blues performers often improvised, either without accompaniment or with only a banjo or guitar. Regional styles of country blues varied widely in the early 20th century. The (Mississippi) Delta blues was a rootsy sparse style with passionate vocals accompanied by slide guitar. The little-recorded Robert Johnson^[68] combined elements of urban and rural blues. In addition to Robert Johnson, influential performers of this style included his predecessors Charley Patton and Son House. Singers such as Blind Willie McTell and Blind Boy Fuller performed in the southeastern "delicate and lyrical" Piedmont blues tradition, which used an elaborate ragtime-based fingerpicking guitar technique. Georgia also had an early slide tradition,^[69] with Curley Weaver, Tampa Red, "Barbecue Bob" Hicks and James "Kokomo" Arnold as representatives of this style.^[70]

The lively Memphis blues style, which developed in the 1920s and 1930s near Memphis, Tennessee, was influenced by jug bands such as the Memphis Jug Band or the Gus Cannon's Jug Stompers. Performers such as Frank Stokes, Sleepy John Estes, Robert Wilkins, Joe McCoy, Casey Bill Weldon and Memphis Minnie used a variety of unusual instruments such as washboard, fiddle, kazoo or mandolin. Memphis Minnie was famous for her virtuoso guitar style. Pianist Memphis Slim began his career in Memphis, but his distinct style was smoother and had some swing elements. Many blues musicians based in Memphis moved to Chicago in the late 1930s or early 1940s and became part of the urban blues movement, which blended country music and electric blues.^[71][72][73]

Bessie Smith, an early blues singer, was known for her powerful voice.

City or urban blues styles were more codified and elaborate as a performer was no longer within their local, immediate community and had to adapt to a larger, more varied audience's aesthetic.^[74] Classic female urban and vaudeville blues singers were popular in the 1920s, among them Mamie Smith, Gertrude "Ma" Rainey, Bessie Smith, and Victoria Spivey. Mamie Smith, more a vaudeville performer than a blues artist, was the first African-American to record a blues in 1920; her second record, "Crazy Blues", sold 75,000 copies in its first month.^[75]

Ma Rainey, the "Mother of Blues", and Bessie Smith each "[sang] around center tones, perhaps in order to project her voice more easily to the back of a room." Smith would "...sing a song in an unusual key, and her artistry in bending and stretching notes with her beautiful, powerful contralto to accommodate her own interpretation was unsurpassed."^[76] Urban male performers included popular black musicians of the era, such Tampa Red, Big Bill Broonzy and Leroy Carr. An important label of this era was the chicagoean Bluebird label. Before WWII, Tampa Red was sometimes referred to as "the Guitar Wizard". Carr accompanied himself on the piano with Scrapper Blackwell on guitar, a format that continued well into the 50s with people such as Charles Brown, and even Nat "King" Cole.^[67]

A typical boogie-woogie bassline

Boogie-woogie was another important style of 1930s and early 1940s urban blues.^[77] While the style is often associated with solo piano, boogie-woogie was also used to accompany singers and, as a solo part, in bands and small combos. Boogie-Woogie style was characterized by a regular bass figure, an ostinato or riff and shifts of level in the left hand, elaborating each chord and trills and decorations in the right hand. Boogie-woogie was pioneered by the Chicago-based Jimmy Yancey and the Boogie-Woogie Trio (Albert Ammons, Pete Johnson and Meade Lux Lewis).^[78] Chicago boogie-woogie performers included Clarence "Pine Top" Smith and Earl Hines, who "linked the propulsive left-hand rhythms of the ragtime pianists with melodic figures similar to those of Armstrong's trumpet in the right hand."^[74] The smooth Louisiana style of Professor Longhair and, more recently, Dr. John blends classic rhythm and blues with blues styles.

Another development in this period was big band blues.^[79] The "territory bands" operating out of Kansas City, the Bennie Moten orchestra, Jay McShann, and the Count Basie Orchestra were also concentrating on the blues, with 12-bar blues instrumentals such as Basie's "One O'Clock Jump" and "Jumpin' at the Woodside" and boisterous "blues shouting" by Jimmy Rushing on songs such as "Going to Chicago" and "Sent for You Yesterday". A well-known big band blues tune is Glenn Miller's "In the Mood". In the 1940s, the jump blues style developed. Jump blues grew up from the boogie woogie wave and was strongly influenced by big band music. It uses saxophone or other brass instruments and the guitar in the rhythm section to create a jazzy, up-tempo sound with declamatory vocals. Jump blues tunes by Louis Jordan and Big Joe Turner, based in Kansas City, Missouri, influenced the development of later styles such as rock and roll and rhythm and blues.^[80] Dallas-born T-Bone Walker, who is often associated with the California blues style,^[81] performed a successful transition from the early urban blues à la Lonnie Johnson and Leroy Carr to the jump blues style and dominated the blues-jazz scene at Los Angeles during the 1940s.^[82]

1950s[link]

The transition from country to urban blues, that began in the 1920s, had always been driven by the successive waves of economic crisis and booms and the associated move of the rural Blacks to urban areas, the Great Migration. The long boom in the aftermath of World War II induced a massive migration of the African American population, the Second Great Migration, which was accompanied by a significant increase of the real income of the urban Blacks. The new migrants constituted a new market for the music industry. The name race record disappeared and was succeeded by Rhythm and Blues. This rapidly evolving market was mirrored by the Billboard Rhythm and Blues Chart. This marketing strategy reinforced trends within urban blues music such as the progressive electrification of the instruments, their amplification and the generalization of the blues beat, the blues shuffle, that became ubiquitous in R&B. This commercial stream had important consequences for blues music which, together with Jazz and Gospel music, became a component of the R&B wave.^[83]

After World War II and in the 1950s, new styles of electric blues music became popular in cities such as Chicago,^[85] Memphis,^[86] Detroit^[87][88] and St. Louis.^[89] Electric blues used electric guitars, double bass (slowly replaced by bass guitar), drums, and harmonica played through a microphone and a PA system or a guitar amplifier. Chicago became a center for electric blues from 1948 on, when Muddy Waters recorded his first success: "I Can't Be Satisfied".^[90] Chicago blues is influenced to a large extent by the Mississippi blues style, because many performers had migrated from the Mississippi region.

Howlin' Wolf,^[91] Muddy Waters,^[92] Willie Dixon,^[93] and Jimmy Reed^[94] were all born in Mississippi and moved to Chicago during the Great Migration. Their style is characterized by the use of electric guitar, sometimes slide guitar, harmonica, and a rhythm section of bass and drums. J. T. Brown who played in Elmore James's bands,^[95] or J. B. Lenoir's^[96] also used saxophones, but these were used more as "backing" or rhythmic support than as solo instruments.

Little Walter and Sonny Boy Williamson (Rice Miller) are well known harmonica (called "harp" by blues musicians) players of the early Chicago blues scene. Other harp players such as Big Walter Horton were also influential. Muddy Waters and Elmore James were known for their innovative use of slide electric guitar. Howlin' Wolf and Muddy Waters were known for their deep, "gravelly" voices.

Bassist and composer Willie Dixon played a major role on the Chicago blues scene. He composed and wrote many standard blues songs of the period, such as "Hoochie Coochie Man", "I Just Want to Make Love to You" (both penned for Muddy Waters) and, "Wang Dang Doodle" and "Back Door Man" for Howlin' Wolf. Most artists of the Chicago blues style recorded for the Chicago-based Chess Records and Checker Records labels. Smaller blues labels of this era included Vee-Jay Records and J.O.B. Records. During the early 1950s, the dominating Chicago labels were challenged by Sam Phillips' Sun Records company in Memphis, which recorded B. B. King and Howlin' Wolf before he moved to Chicago in 1960.^[97] After Phillips discovered Elvis Presley in 1954, the Sun label turned to the rapidly expanding white audience and started recording mostly rock 'n' roll.^[98]

In the 1950s, blues had a huge influence on mainstream American popular music. While popular musicians like Bo Diddley^[87] and Chuck Berry,^[99] both recording for Chess, were influenced by the Chicago blues, their enthusiastic playing styles departed from the melancholy aspects of blues. Chicago blues also influenced Louisiana's zydeco music,^[100] with Clifton Chenier^[101] using blues accents. Zydeco musicians used electric solo guitar and cajun arrangements of blues standards.

Overseas, in England, electric blues took root there during a much acclaimed Muddy Waters tour. Waters, unsuspecting of his audience's tendency towards skiffle, an acoustic, softer brand of blues, turned up his amp and started to play his Chicago brand of electric blues. Although the audience was largely jolted by the performance, the performance influenced local musicians such as Alexis Korner and Cyril Davies to emulate this louder style, inspiring the British invasion of the Rolling Stones and the Yardbirds.^[102]

In the late 1950s, a new blues style emerged on Chicago's West Side pioneered by Magic Sam, Buddy Guy and Otis Rush on Cobra Records.^[103] The 'West Side Sound' had strong rhythmic support from a rhythm guitar, bass guitar and drums and as pefected by Guy, Freddie King, Magic Slim and Luther Allison was dominated by amplified electric lead guitar.^[104][105]

Other blues artists, such as John Lee Hooker had influences not directly related to the Chicago style. John Lee Hooker's blues is more "personal", based on Hooker's deep rough voice accompanied by a single electric guitar. Though not directly influenced by boogie woogie, his "groovy" style is sometimes called "guitar boogie". His first hit, "Boogie Chillen", reached #1 on the R&B charts in 1949.^[106]

By the late 1950s, the swamp blues genre developed near Baton Rouge, with performers such as Lightnin' Slim,^[107] Slim Harpo,^[108] Sam Myers and Jerry McCain around the producer J. D. "Jay" Miller and the Excello label. Strongly influenced by Jimmy Reed, Swamp blues has a slower pace and a simpler use of the harmonica than the Chicago blues style performers such as Little Walter or Muddy Waters. Songs from this genre include "Scratch my Back", "She's Tough" and "I'm a King Bee". Alan Lomax's recordings of Mississippi Fred McDowell would eventually bring him wider attention on both the blues and folk circuit, with McDowell's droning style influencing North Mississippi hill country blues musicians.^[109]

1960s and 1970s[link]

By the beginning of the 1960s, genres influenced by African American music such as rock and roll and soul were part of mainstream popular music. White performers had brought African-American music to new audiences, both within the US and abroad. However, the blues wave that brought artists such as Muddy Waters to the foreground had stopped. Bluesmen such as Big Bill Broonzy and Willie Dixon started looking for new markets in Europe. Dick Waterman and the blues festivals he organized in Europe played a major role in propagating blues music abroad. In the UK, bands emulated US blues legends, and UK blues-rock-based bands had an influential role throughout the 1960s.^[110]

Blues performers such as John Lee Hooker and Muddy Waters continued to perform to enthusiastic audiences, inspiring new artists steeped in traditional blues, such as New York–born Taj Mahal. John Lee Hooker blended his blues style with rock elements and playing with younger white musicians, creating a musical style that can be heard on the 1971 album Endless Boogie. B. B. King's virtuoso guitar technique earned him the eponymous title "king of the blues".

In contrast to the Chicago style, King's band used strong brass support from a saxophone, trumpet, and trombone, instead of using slide guitar or harp. Tennessee-born Bobby "Blue" Bland, like B. B. King, also straddled the blues and R&B genres. During this period, Freddie King and Albert King often played with rock and soul musicians (Eric Clapton, Booker T & the MGs) and had a major influence on those styles of music.

The music of the Civil Rights^[111] and Free Speech movements in the US prompted a resurgence of interest in American roots music and early African American music. As well as Jimmi Bass Music festivals such as the Newport Folk Festival^[112] brought traditional blues to a new audience, which helped to revive interest in prewar acoustic blues and performers such as Son House, Mississippi John Hurt, Skip James, and Reverend Gary Davis.^[111] Many compilations of classic prewar blues were republished by the Yazoo Records. J. B. Lenoir from the Chicago blues movement in the 1950s recorded several LPs using acoustic guitar, sometimes accompanied by Willie Dixon on the acoustic bass or drums. His songs, originally distributed in Europe only,^[113] commented on political issues such as racism or Vietnam War issues, which was unusual for this period. His Alabama Blues recording had a song that stated:

I never will go back to Alabama, that is not the place for me (2x)
You know they killed my sister and my brother,
and the whole world let them peoples go down there free

White audiences' interest in the blues during the 1960s increased due to the Chicago-based Paul Butterfield Blues Band and the British blues movement. The style of British blues developed in the UK, when bands such as The Animals, Fleetwood Mac, John Mayall & the Bluesbreakers, The Rolling Stones, The Yardbirds, and Cream and Irish musician Rory Gallagher performed classic blues songs from the Delta or Chicago blues traditions.^[114] Many of Led Zeppelin's earlier hits were renditions of traditional blues songs.

The British and blues musicians of the early 1960s inspired a number of American blues rock fusion performers, including Canned Heat, the early Jefferson Airplane, Janis Joplin, Johnny Winter, The J. Geils Band, Ry Cooder, and The Allman Brothers Band. One blues rock performer, Jimi Hendrix, was a rarity in his field at the time: a black man who played psychedelic rock. Hendrix was a skilled guitarist, and a pioneer in the innovative use of distortion and feedback in his music.^[115] Through these artists and others, blues music influenced the development of rock music.^[116]

Santana, which was originally called the Carlos Santana Blues Band, also experimented with Latin-influenced blues and blues-rock music around this time. At the end of the 1950s appeared the very bluesy Tulsa Sound merging rock'n'roll, jazz and country influences. This particular music style started to be broadly popularized within the 1970s by J.J. Cale and the cover versions performed by Eric Clapton of "After Midnight" and "Cocaine".

In the early 1970s, The Texas rock-blues style emerged, which used guitars in both solo and rhythm roles. In contrast with the West Side blues, the Texas style is strongly influenced by the British rock-blues movement. Major artists of the Texas style are Johnny Winter, Stevie Ray Vaughan, The Fabulous Thunderbirds, and ZZ Top. These artists all began their musical journey in the 1970s, but they did not achieve major international success until the next decade.^[117]

1980s to the 2000s[link]

Texas blues guitarist Stevie Ray Vaughan

Since at least the 1980s, there has been a resurgence of interest in the blues among a certain part of the African-American population, particularly around Jackson, Mississippi and other deep South regions. Often termed "soul blues" or "Southern soul", the music at the heart of this movement was given new life by the unexpected success of two particular recordings on the Jackson-based Malaco label:^[118] Z. Z. Hill's Down Home Blues (1982) and Little Milton's The Blues is Alright (1984). Contemporary African-American performers who work this vein of the blues include Bobby Rush, Denise LaSalle, Sir Charles Jones, Bettye LaVette, Marvin Sease, Peggy Scott-Adams, Mel Waiters, Clarence Carter, Dr. "Feelgood" Potts, O.B. Buchana, Ms. Jody, Shirley Brown, and dozens of others.

During the 1980s, blues also continued in both traditional and new forms. In 1986, the album Strong Persuader revealed Robert Cray as a major blues artist.^[119] The first Stevie Ray Vaughan recording, Texas Flood, was released in 1983, and the Texas-based guitarist exploded onto the international stage. 1989 saw a revival of John Lee Hooker's popularity with the album The Healer. Eric Clapton, known for his performances with the Blues Breakers and Cream, made a comeback in the 1990s with his album Unplugged, in which he played some standard blues numbers on acoustic guitar. However, beginning in the 1990s, digital multitrack recording and other technological advances and new marketing strategies that include video clip production have increased costs, and challenge the spontaneity and improvisation that are an important component of blues music.^[120]

In the 1980s and 1990s, blues publications such as Living Blues and Blues Revue began to be distributed, major cities began forming blues societies, outdoor blues festivals became more common, and^[121] more nightclubs and venues for blues emerged.^[122]

In the 1990s, largely ignored hill country blues gained minor recognition in both blues and alternative rock music circles with North Mississippi artists R. L. Burnside and Junior Kimbrough.^[109] Blues performers explored a range of musical genres, as can be seen, for example, from the broad array of nominees of the yearly Blues Music Awards, previously named W. C. Handy Awards^[123] or of the Grammy Awards for Best Contemporary and Traditional Blues Album. The Bilboard Blues Album chart monitors and therefore provides an overview over the current blues production. Contemporary blues music is nurtured by several blues labels such as: Alligator Records, Ruf Records, Severn Records, Chess Records (MCA), Delmark Records, NorthernBlues Music, Fat Possum Records and Vanguard Records (Artemis Records). Some labels are famous for their rediscovering and remastering of blues rarities such as Arhoolie Records, Smithsonian Folkways Recordings (heir of Folkways Records) and Yazoo Records (Shanachie Records).^[124]

Musical impact[link]

Blues musical styles, forms (12-bar blues), melodies, and the blues scale have influenced many other genres of music, such as rock and roll, jazz, and popular music.^[125] Prominent jazz, folk or rock performers, such as Louis Armstrong, Duke Ellington, Miles Davis, and Bob Dylan have performed significant blues recordings. The blues scale is often used in popular songs like Harold Arlen's "Blues in the Night", blues ballads like "Since I Fell for You" and "Please Send Me Someone to Love", and even in orchestral works such as George Gershwin's "Rhapsody in Blue" and "Concerto in F". Gershwin's second "Prelude" for solo piano is an interesting example of a classical blues, maintaining the form with academic strictness. The blues scale is ubiquitous in modern popular music and informs many modal frames, especially the ladder of thirds used in rock music (for example, in "A Hard Day's Night"). Blues forms are used in the theme to the televised Batman, teen idol Fabian's hit, "Turn Me Loose", country music star Jimmie Rodgers' music, and guitarist/vocalist Tracy Chapman's hit "Give Me One Reason".

R&B music can be traced back to spirituals and blues. Musically, spirituals were a descendant of New England choral traditions, and in particular of Isaac Watts's hymns, mixed with African rhythms and call-and-response forms. Spirituals or religious chants in the African-American community are much better documented than the "low-down" blues. Spiritual singing developed because African-American communities could gather for mass or worship gatherings, which were called camp meetings.

Early country bluesmen such as Skip James, Charley Patton, Georgia Tom Dorsey played country and urban blues and had influences from spiritual singing. Dorsey helped to popularize Gospel music.^[126] Gospel music developed in the 1930s, with the Golden Gate Quartet. In the 1950s, soul music by Sam Cooke, Ray Charles and James Brown used gospel and blues music elements. In the 1960s and 1970s, gospel and blues were these merged in soul blues music. Funk music of the 1970s was influenced by soul; funk can be seen as an antecedent of hip-hop and contemporary R&B.

Duke Ellington straddled the big band and bebop genres. Ellington extensively used the blues form.^[127]

Before World War II, the boundaries between blues and jazz were less clear. Usually jazz had harmonic structures stemming from brass bands, whereas blues had blues forms such as the 12-bar blues. However, the jump blues of the 1940s mixed both styles. After WWII, blues had a substantial influence on jazz. Bebop classics, such as Charlie Parker's "Now's the Time", used the blues form with the pentatonic scale and blue notes. Bebop marked a major shift in the role of jazz, from a popular style of music for dancing, to a "high-art," less-accessible, cerebral "musician's music". The audience for both blues and jazz split, and the border between blues and jazz became more defined.^[127][128]

The blues' 12-bar structure and the blues scale was a major influence on rock and roll music. Rock and roll has been called "blues with a backbeat"; Carl Perkins called rockabilly "blues with a country beat". Rockabillies were also said to be 12-bar blues played with a bluegrass beat. "Hound Dog", with its unmodified 12-bar structure (in both harmony and lyrics) and a melody centered on flatted third of the tonic (and flatted seventh of the subdominant), is a blues song transformed into a rock and roll song. Jerry Lee Lewis's style of rock and roll was heavily influenced by the blues and its derivative boogie woogie. His style of music was not exactly rockabilly but it has been often called real rock and roll (this is a label he shares with several African American rock and roll performers).^[129][130]

Early country music was infused with the blues.^[131] Jimmie Rodgers, Moon Mullican, Bob Wills, Bill Monroe and Hank Williams have all described themselves as blues singers and their music has a blues feel that is different to the country pop of Eddy Arnold. A lot of the 1970s-era "outlaw" country music by Willie Nelson and Waylon Jennings also borrowed from the blues. When Jerry Lee Lewis returned to country after the decline of 1950s style rock and roll, he sang his country with a blues feel and often included blues standards on his albums.

Many early rock and roll songs are based on blues: "That's All Right Mama", "Johnny B. Goode", "Blue Suede Shoes", "Whole Lotta Shakin' Goin On", "Shake, Rattle, and Roll", and "Long Tall Sally". The early African American rock musicians retained the sexual themes and innuendos of blues music: "Got a gal named Sue, knows just what to do" ("Tutti Frutti", Little Richard) or "See the girl with the red dress on, She can do the Birdland all night long" ("What'd I Say", Ray Charles). The 12-bar blues structure can be found even in novelty pop songs, such as Bob Dylan's "Obviously Five Believers" and Esther and Abi Ofarim's "Cinderella Rockefella".

In popular culture[link]

Like jazz, rock and roll, heavy metal music, hip hop music, reggae, country music, and pop music, blues has been accused of being the "devil's music" and of inciting violence and other poor behavior.^[132] In the early 20th century, the blues was considered disreputable, especially as white audiences began listening to the blues during the 1920s.^[65] In the early twentieth century, W.C. Handy was the first to popularize blues-influenced music among non-black Americans.

During the blues revival of the 1960s and '70s, acoustic blues artist Taj Mahal and legendary Texas bluesman Lightnin' Hopkins wrote and performed music that figured prominently in the popularly and critically acclaimed film Sounder (1972). The film earned Mahal a Grammy nomination for Best Original Score Written for a Motion Picture and a BAFTA nomination.^[133] Almost 30 years later, Mahal wrote blues for, and performed a banjo composition, claw-hammer style, in the 2001 movie release Songcatcher, which focused on the story of the preservation of the roots music of Appalachia.

Perhaps the most visible example of the blues style of music in the late 20th century came in 1980, when Dan Aykroyd and John Belushi released the film The Blues Brothers. The film drew many of the biggest living influencers of the Rhythm and blues genre together, such as Ray Charles, James Brown, Cab Calloway, Aretha Franklin, and John Lee Hooker. The band formed also began a successful tour under the Blues Brothers marquee. 1998 brought a sequel, Blues Brothers 2000 that, while not holding as great a critical and financial success, featured a much larger number of blues artists, such as B.B. King, Bo Diddley, Erykah Badu, Eric Clapton, Steve Winwood, Charlie Musselwhite, Blues Traveller, Jimmie Vaughan, Jeff Baxter.

In 2003, Martin Scorsese made significant efforts to promote the blues to a larger audience. He asked several famous directors such as Clint Eastwood and Wim Wenders to participate in a series of documentary films for PBS called The Blues.^[134] He also participated in the rendition of compilations of major blues artists in a series of high-quality CDs. Blues guitarist and vocalist Keb' Mo' performed his blues rendition of "America, the Beautiful" in 2006 to close out the final season of the television series The West Wing.
