Harmony

In music, harmony is the use of simultaneous pitches (tones, notes), or chords. The study of harmony involves chords and their construction and chord progressions and the principles of connection that govern them. Harmony is often said to refer to the "vertical" aspect of music, as distinguished from melodic line, or the "horizontal" aspect.Counterpoint, which refers to the interweaving of melodic lines, and polyphony, which refers to the relationship of separate independent voices, are thus sometimes distinguished from harmony.

In popular and jazz harmony, chords are named by their root plus various terms and characters indicating their qualities. In many types of music, notably baroque, romantic, modern, and jazz, chords are often augmented with "tensions". A tension is an additional chord member that creates a relatively dissonant interval in relation to the bass. Typically, in the classical common practice period a dissonant chord (chord with tension) "resolves" to a consonant chord. Harmonization usually sounds pleasant to the ear when there is a balance between the consonant and dissonant sounds. In simple words, that occurs when there is a balance between "tense" and "relaxed" moments.

A cappella

A cappella [a kapˈpɛlla] (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.

Religious origins

A cappella music was originally used in religious music, especially church music as well as anasheed and zemirot. Gregorian chant is an example of a cappella singing, as is the majority of secular vocal music from the Renaissance. The madrigal, up until its development in the early Baroque into an instrumentally-accompanied form, is also usually in a cappella form. Jewish and Christian music were originally a cappella, and this practice has continued in both of these religions as well as in Islam.

Swing Low, Sweet Chariot

"Swing Low, Sweet Chariot" is an American negro spiritual. The earliest known recording was in 1909, by the Fisk Jubilee Singers of Fisk University. It is also the anthem of the England national rugby union team.

In 2002, the Library of Congress honored the song as one of 50 recordings chosen that year to be added to the National Recording Registry. It was also included in the list of Songs of the Century, by the Recording Industry Association of America and the National Endowment for the Arts.

History

"Swing Low, Sweet Chariot" may have been written by Wallis Willis, a Choctaw freedman in the old Indian Territory in what is now Choctaw County, near the County seat of Hugo, Oklahoma sometime before 1862. He was inspired by the Red River, which reminded him of the Jordan River and of the Prophet Elijah's being taken to heaven by a chariot (2 Kings 2:11). Some sources claim that this song and "Steal Away" (also sung by Willis) had lyrics that referred to the Underground Railroad, the freedom movement that helped blacks escape from Southern slavery to the North and Canada.

Thinking of You (I Drive Myself Crazy)

"Thinking of You (I Drive Myself Crazy)" (titled "I Drive Myself Crazy" in the United States), is the seventh single released in the German market and the fourth from American boy band NSYNC's self-titled debut album. The track was also featured on the group's seasonal European album, The Winter Album. The song made its first appearance on the American and British versions of the band's self-titled debut album. The single did not perform as well on the charts, selling less than 150,000 copies. The song is notable as being one of the few songs where someone other than Justin Timberlake and JC Chasez sang lead vocals—Chris Kirkpatrick sings the first verse in the U.S. version, while in the European version, Chasez sang Kirkpatrick's part.
