Trance is a genre of electronic dance music that developed in the 1990s in Germany.[5] It is characterized by a tempo of between 125 and 150 beats per minute,[5] repeating melodic phrases,[5] and a musical form that builds up and down throughout a track.[5] Trance is a genre on its own, but also will include other styles of electronic music such as techno,[3] house,[1] pop,[3] chill-out,[3] classical music,[3][4] and film music.[4]

Trance refers to an induced emotional feeling, high, euphoria, chills, and uplifting rush listeners experience. A characteristic of virtually all trance songs is the soft mid-song breakdown,[3][5] beginning with and occurring after the orchestration is broken down and the rhythm tracks fade out rapidly, leaving the melody, atmospherics, or both to stand alone for anywhere from a few seconds to a few minutes. Another common characteristic would be the use of vocals often sung by a female voice ranging from mezzo-soprano to soprano. Less often, the female vocals may be in a grand, soaring, or operatic style, which has been described as "ethereal female leads floating amongst the synths"
