Bach wrote many cantatas but none have maintained the popularity as this excerpt from No. 140 often called Sleepers Awake." This is most likely due to the elegant, flowing nature of the writing that is so distinctly Bach. The solo part alternates the sustained line with the more technical line which provides interest in sound and interest in playing. "Wachet Auf" from Cantata 140 is arranged by David Marlatt for saxophone quartet (AATB).".
