The Origins of Vocal Trance Today...

Vocal trance is a sub-genre of trance music that focuses on vocals and melodies. The sub-genre came into existence in the early 1990's, when trance was still developing. Although many early trance records used vocal samples mixed in with the beats, the earliest examples of the style appeared in 1992-1993.

A typical track consists of three elements, though later tracks labeled vocal trance may not include all of them. A track begins with an intro of progressive beats. The melodic part starts incrementally, combining vocals, usually female, a melodic sound (for the most part high pitched and fast), and a bass pattern. Towards the end of the track, the melody fades out and the intro rhythm returns, usually with some minor changes.

Vocal trance producers frequently make use of session musicians, particularly females, for vocals on their tracks. Session vocalists have been featured on tracks that span different genres and sub genres, while some vocalists have chosen to work only within the electronic club and dance music genres.

Vocal trance was popular in Europe, notably Germany, Austria, Sweden, Netherlands, Belgium and Great Britain until 2004. SOURCE
