 At its premiere, the piece initially had 10 sections, a live vocal chorus, and was an over an hour in duration, and included 2 soloists.Sections were removed as the work evolved, and an extensive tour sponsored by the U.S. Department in 1962 forced Ailey to commit the music for "Revelations" to recording.The dance then solidified into the three-part format seen today with a duration of 36 minutes.
