Trance is a genre of electronic dance music characterized by a tempo between 120 and 150 beats per minute, repeating melodic phrases, and a musical form that builds tension and elements throughout a track, often culminating in one or two "peaks" or "drops." Trance incorporates influences from other musical styles like techno, house, chill-out, classical music, and film scores. The music often features a mid-song climax followed by a breakdown, emphasizing melody and atmospherics before building up again. While mostly instrumental, vocals, often by female soloists, can be incorporated, forming the subgenre of vocal trance.
