Music in Eight Parts was composed in 1970, but was quickly withdrawn from Glass’ catalogue and replaced by Music in Twelve Parts, until it was revived in 2018 when the manuscript was discovered at an auction. This edition of Music in Eight Parts is adapted for flexible instrumentation. Parts are included in C (in the appropriate clef as well as alto clef), and in B-flat, E-flat, and F transpositions. Additionally, 4 keyboard parts that are each a combination of 2 lines are included.
