Trance

Trance is a genre of electronic music that emerged during the early 1990s in Germany and the rest of Europe, as a more melodic offshoot from techno. It is characterized by a tempo lying between 125 and 150 beats per minute (BPM), repeating melodic phrases, and a musical form that distinctly builds tension and elements throughout a track often culminating in 1 to 2 “peaks” or “drops.” Although trance is a genre of its own, it liberally incorporates influences from other musical styles such as techno, house, pop, chill-out, classical music, tech house, ambient, and film music.
 
A trance refers to a state of hypnotism and heightened consciousness. This is portrayed in trance music by the mixing of layers with distinctly foreshadowed build-up and release. A common characteristic of trance music is a mid-song climax followed by a soft breakdown disposing of beats and percussion entirely, leaving the melody or atmospherics to stand alone for an extended period before gradually building up again. Trance tracks are often lengthy to allow for such progression and commonly have sufficiently sparse opening and closing sections to facilitate mixing by DJs.
 
Trance can be purely instrumental, although vocals are also a common feature. Typically they are performed by mezzo-soprano to soprano female soloists, often without a traditional verse/chorus structure. Structured vocal form in trance music forms the basis of the vocal trance subgenre, which has been described as “grand, soaring, and operatic” and “ethereal female leads floating amongst the synths”.
