Trance is a style of electronic music that developed in the 1990s. Trance music is generally characterized by a tempo of between 130 and 150 bpm, featuring repeating melodic synthesizer phrases, and a musical form that builds up and down throughout a track, it often features crescendos and/or breakdowns. Sometimes vocals are also utilized. The style is arguably derived from a combination of largely electronic music such as ambient music, techno, and house. As this music is almost always played in nightclubs at popular vacation spots and in inner cities, trance can be understood as a form of club music.
