Electronic dance music

Electronic dance music (EDM), also referred to as dance music or club music, is a broad range of percussive electronic music genres originally made for nightclubs, raves, and festivals. It is generally produced for playback by DJs who create seamless selections of tracks, called a DJ mix, by segueing from one recording to another. EDM producers also perform their music live in a concert or festival setting in what is sometimes called a live PA. Since its inception EDM has expanded to include a wide range of subgenres.

During the late 1980s to early 1990s, following the emergence of electronic music instruments, rave culture, pirate radio, party crews, underground festivals, and an upsurge of interest in club culture, EDM achieved mainstream popularity in Europe and Japan. However, rave culture was not as broadly popular in the United States; it was not typically seen outside of the regional scenes in New York City, Florida, the Midwest, and California. Although the pioneer genres of electro, Chicago house and Detroit techno were influential both in Europe and the United States, mainstream media outlets and the record industry in the United States remained openly hostile to it until the 1990s and beyond. There was also a perceived association between EDM and drug culture, which led governments at state and city levels to enact laws and policies intended to halt the spread of rave culture.

Subsequently, in the new millennium, the popularity of EDM increased globally, particularly in the United States and Australia. By the early 2010s, the term "electronic dance music" and the initialism "EDM" was being pushed by the American music industry and music press in an effort to rebrand American rave culture. Despite the industry's attempt to create a specific EDM brand, the name remains in use as an umbrella term for multiple genres, including dance-pop, house, techno, electro and trance, as well as their respective subgenres, which all predate the name.

Various EDM genres have evolved over the last 40 years, for example; house, techno, drum and bass, dance-pop etc. Stylistic variation within an established EDM genre can lead to the emergence of what is called a subgenre. Hybridization, where elements of two or more genres are combined, can lead to the emergence of an entirely new genre of EDM.

In the late 1960s bands such as Silver Apples created electronic music intended for dancing. Other early examples of music that influenced later electronic dance music include Jamaican dub music during the late 1960s to 1970s, the synthesizer-based disco music of Italian producer Giorgio Moroder in the late 1970s, and the electropop of Kraftwerk and Yellow Magic Orchestra in the mid-to-late 1970s.

Author Michael Veal considers dub music, a Jamaican music stemming from roots reggae and sound system culture that flourished between 1968 and 1985, to be one of the important precursors to contemporary electronic dance music. Dub productions were remixed reggae tracks that emphasized rhythm, fragmented lyrical and melodic elements, and reverberant textures. The music was pioneered by studio engineers, such as King Tubby, Errol Thompson, Lee "Scratch" Perry, and Scientist. Their productions included forms of tape editing and sound processing that Veal considers comparable to techniques used in musique concrète. Dub producers made improvised deconstructions of existing multi-track reggae mixes by using the studio mixing board as a performance instrument. They also foregrounded spatial effects such as reverb and delay by using auxiliary send routings creatively. The Roland Space Echo, manufactured by Roland Corporation, was widely used by dub producers in the 1970s to produce echo and delay effects.

Despite the limited electronic equipment available to dub pioneers such as King Tubby and Lee "Scratch" Perry, their experiments in remix culture were musically cutting-edge. Ambient dub was pioneered by King Tubby and other Jamaican sound artists, using DJ-inspired ambient electronics, complete with drop-outs, echo, equalization and psychedelic electronic effects. It featured layering techniques and incorporated elements of world music, deep bass lines and harmonic sounds. Techniques such as a long echo delay were also used.

Hip-hop has had some influence in the development of electronic dance music since the 1970s. Inspired by Jamaican sound system culture Jamaican-American DJ Kool Herc introduced large bass heavy speaker rigs to the Bronx. His parties are credited with having kick-started the New York City hip-hop movement in 1973. A technique developed by DJ Kool Herc that became popular in hip-hop culture was playing two copies of the same record on two turntables, in alternation, and at the point where a track featured a break. This technique was further used to manually loop a purely percussive break, leading to what was later called a break beat.
