Vocal trance is a subgenre of trance music developed in Germany. It contains vocals, highly melodic sessions, intro/outros which are similar to those of hard trance or progressive trance and tracks of usually about 6 to 8 minutes long. The sub-genre goes back to the early 1990s, when trance was still developing, and vocals have gone onto become a staple of trance. Although many early trance records used vocal samples mixed in with the beats, the earliest examples of the style appeared in 1992/93. Read more on Last.fm.
