There are several types of disc jockeys. Radio DJs introduce and play music that is broadcast on AM, FM, shortwave, digital, or internet radio stations. Club DJs select and play music in bars, nightclubs, discothèques, at raves, or even in a stadium. Hip hop disc jockeys select and play music using multiple turntables, often to back up one or more MCs, and they may also do turntable scratching to create percussive sounds. In reggae, the disc jockey (deejay) is a vocalist who raps, "toasts", or chats over pre-recorded rhythm tracks while the individual choosing and playing them is referred to as a selector. Mobile DJs travel with portable sound systems and play recorded music at a variety of events.
DJ equipment may consist of:
Several techniques are used by DJs as a means to better mix and blend recorded music. These techniques primarily include the cueing, equalization, and audio mixing of two or more sound sources. The complexity and frequency of special techniques depends largely on the setting in which a DJ is working. Radio DJs are less likely to focus on music-mixing procedures than club DJs, who rely on a smooth transition between songs using a range of techniques.
Club DJ turntable techniques include beatmatching, phrasing, and slip-cueing to preserve energy on a dancefloor. Turntablism embodies the art of cutting, beat juggling, scratching, needle drops, phase shifting, back spinning, and more to perform the transitions and overdubs of samples in a more creative manner (although turntablism is often considered a use of the turntable as a musical instrument rather than a tool for blending recorded music). Professional DJs may use harmonic mixing to choose songs that are in compatible musical keys.
The world's first radio disc jockey was Ray Newby, of Stockton, California. In 1909, at 16 years of age, Newby began regularly playing records on a small spark transmitter while a student at Herrold College of Engineering and Wireless, located in San Jose, California, under the authority of radio pioneer Charles "Doc" Herrold. Though it was really called Disco Jockey, it has been changed through the years to Disc Jockey but it can be referred as DISCO or DISC Jockey.
By 1910, regular radio broadcasting had started to use "live" as well as prerecorded sound. In the early radio age, content typically included comedy, drama, news, music, and sports reporting. The on-air announcers and programmers would later be known as disc jockeys. In the 1920s, juke joints became popular as places for dancing and drinking to recorded jukebox music. In 1927, Christopher Stone became the first radio announcer and programmer in the United Kingdom, on the BBC radio station. In 1929, Thomas Edison ceased phonograph cylinder manufacture, ending the disc and cylinder rivalry.
Prior to this, most music heard on radio was live; most radio stations had an orchestra or band on the payroll. The Federal Communications Commission also clearly favored live music, providing accelerated license approval to stations promising not to use any recordings for their first three years on the air.
In the 1950s, American radio DJs would appear live at "sock hops" and "platter parties" and assume the role of a human jukebox. They would usually play 45-rpm records, featuring hit singles on one turntable while talking between songs. In some cases, a live drummer was hired to play beats between songs to maintain the dance floor. In 1955, Bob Casey, a well-known "sock hop" DJ, brought the two-turntable system to the U.S. Throughout the 1950s, payola payments by record companies to DJs in return for airplay were an ongoing problem. Part of the fallout from the payola scandal was tighter control of the music by station management. The Top 40 format emerged, where popular songs are played repeatedly.
In the late 1950s, sound systems, a new form of public entertainment, were developed in the ghettos of Kingston, Jamaica. Promoters, who called themselves DJs, would throw large parties in the streets that centered on the disc jockey, called the "selector," who played dance music from large, loud PA systems and bantered over the music with a boastful, rhythmic chanting style called "toasting". These parties quickly became profitable for the promoters, who would sell admission, food, and alcohol, leading to fierce competition between DJs for the biggest sound systems and newest records.
By 1968, the number of dance clubs started to decline; most American clubs either closed or were transformed into clubs featuring live bands. Neighborhood block parties that were modelled after Jamaican sound systems gained popularity in Europe and in the boroughs of New York City.
In 1973, Jamaican-born DJ Kool Herc, widely regarded as the "father of hip-hop culture," performed at block parties in his Bronx neighborhood and developed a technique of mixing back and forth between two identical records to extend the rhythmic instrumental segment, or break. Turntablism, the art of using turntables not only to play music but to manipulate sound and create original music, began to develop.
In 1974, Technics released the first SL-1200 turntable, which evolved into the SL-1200 MK2 in 1979—which, as of the early-2010s, remains the industry standard for deejaying. In 1974, German electronic music band Kraftwerk released the 22-minute song "Autobahn," which takes up the entire first side of that LP. Years later, Kraftwerk would become a significant influence on hip-hop artists such as Afrika Bambaataa and house music pioneer Frankie Knuckles. During the mid-1970s, Hip-hop music and culture began to emerge, originating among urban African Americans and Latinos in New York City. The four main elements of Hip Hop culture are graffiti, DJing, breakdancing, and MCing (rapping).
In the mid-1970s, the soul-funk blend of dance pop known as disco took off in the mainstream pop charts in the United States and Europe, causing discothèques to experience a rebirth. Unlike many late-1960s clubs, which featured live bands, discothèques used the DJ's selection and mixing of records as the entertainment. In 1975, record pools began, providing disc jockeys access to newer music from the industry in an efficient method.
In 1975, hip-hop DJ Grand Wizard Theodore invented the scratching technique by accident. In 1976, American DJ, editor, and producer Walter Gibbons remixed "Ten Percent" by Double Exposure, one of the earliest commercially released 12″ singles (aka "maxi-single"). In 1979, the Sugar Hill Gang released "Rapper's Delight", the first hip-hop record to become a hit. It was also the first real breakthrough for sampling, as the bassline of Chic's "Good Times" laid the foundation for the song.
In 1977, Saratoga Springs, NY disc jockey Tom L. Lewis introduced the Disco Bible (later renamed Disco Beats), which published hit disco songs listed by beats per minute (tempo), as well as by either artist or song title. Billboard ran an article on the new publication, and it went national relatively quickly. The list made it easier for beginning DJs to learn how to create seamless transitions between songs without dancers having to change their rhythm on the dance floor. Today, DJs can find the beats per minute of songs in the BPM List.
In the early 1980s, NYC disco DJ Larry Levan, known for his eclectic mixes, gained a cult following, and the Paradise Garage, the nightclub at which he spun, became the prototype for the modern dance club where the music and the DJ were showcased. Around the same time, the disco-influenced electronic style of dance music called house music emerged in Chicago. The name was derived from the Warehouse Club in Chicago, where resident DJ Frankie Knuckles mixed old disco classics and Eurosynth pop. House music is essentially disco music with electronic drum machine beats. The common element of most house music is a 4/4 beat generated by a drum machine or other electronic means (such as a sampler), together with a solid (usually also electronically generated) synth bassline. In 1983, Jesse Saunders released what some consider the first house music track, "On & On." The mid-1980s also saw the emergence of New York Garage, a house music hybrid that was inspired by Levan's style and sometimes eschewed the accentuated high-hats of the Chicago house sound.
During the mid-1980s, techno music emerged from the Detroit club scene. Being geographically located between Chicago and New York, Detroit techno artists combined elements of Chicago house and New York garage along with European imports. Techno distanced itself from disco's roots by becoming almost purely electronic with synthesized beats. In 1985, the Winter Music Conference started in Fort Lauderdale Florida and became the premier electronic music conference for dance music disc jockeys.
In 1985, TRAX Dance Music Guide was launched by American Record Pool in Beverly Hills. It was the first national DJ-published music magazine, created on the Macintosh computer using extensive music market research and early desktop publishing tools. In 1986, "Walk This Way", a rap/rock collaboration by Run DMC and Aerosmith, became the first hip-hop song to reach the Top 10 on the Billboard Hot 100. This song was the first exposure of hip-hop music, as well as the concept of the disc jockey as band member and artist, to many mainstream audiences. In 1988, DJ Times magazine was first published. It was the first US-based magazine specifically geared toward the professional mobile and club DJ.
Starting in the mid-1980s, the wedding and banquet business changed dramatically with the introduction of DJ music, replacing the bands that had been the norm. Bandleaders, like Jerry Perell and others, started DJ companies, such as NY Rhythm DJ Entertainers. Using their knowledge of audience participation, MC charisma, and "crowd-pleasing" repertory selection, the wedding music industry became almost all DJ while combining the class and elegance of the traditional band presentation. New DJs as well as bandleaders with years of experience and professionalism transformed the entire industry.
In 1991, Mobile Beat magazine, geared specifically toward mobile DJs, began publishing. In 1992, MPEG which stands for the Moving Picture Experts Group, released The MPEG-1 standard, designed to produce reasonable sound at low bit rates. The lossy compression scheme MPEG-1 Layer-3, popularly known as MP3, later revolutionized the digital music domain. In 1993, the first internet "radio station", Internet Talk Radio, was developed by Carl Malamud. Because the audio was relayed over the internet, it was possible to access internet radio stations from anywhere in the world. This made it a popular service for both amateur and professional disc jockeys operating from a personal computer.
In 1995, the first full-time, internet-only radio station, Radio HK, began broadcasting the music of independent bands. In 1996, Mobile Beat had its first national mobile DJ convention in Las Vegas. During the late 1990s, nu metal bands, such as Korn, Limp Bizkit, and Linkin Park, reached the height of their popularity. This new subgenre of alternative rock bore some influence from hip-hop because rhythmic innovation and syncopation are primary, often featuring DJs as band members. As well, during the late 1990s, various DJ and VJ software programs were developed, allowing personal computer users to deejay or veejay using his or her personal music or video files.
In 1998, the first MP3 digital audio player was released, the Eiger Labs MPMan F10. Final Scratch debuted at the BE Developer Conference, marking the first digital DJ system to allow DJs control of MP3 files through special time-coded vinyl records or CDs. While it would take sometime for this novel concept to catch on with the "die hard Vinyl DJs", This would soon become the first step in the new Digital DJ revolution. Manufacturers joined with computer DJing pioneers to offer professional endorsements, the first being Professor Jam (aka William P. Rader), who went on to develop the industry's first dedicated computer DJ convention and learning program, the "CPS (Computerized Performance System) DJ Summit", to help spread the word about the advantages of this emerging technology.
In 1999, Shawn Fanning released Napster, the first of the massively popular peer-to-peer file sharing systems. During this period, the AVLA (Audio Video Licensing Agency) of Canada announced an MP3 DJing license, administered by the Canadian Recording Industry Association. This meant that DJs could apply for a license giving them the right to perform publicly using music stored on a hard drive, instead of having to cart their whole CD collections around to their gigs.
