This is the Shaker tune made famous by Aaron Copland in 'Appalachian Spring.' A descant, largely on the mixolydian scale (i.e. doh-re-mi-fa-sol-la-TE-doh) accompanies the melody, which can be sung or played instrumentally.

The composer performs on the accompanying recording with boy soprano, A.S. (Note that the score provided here is a revision and does not exactly correspond to the recording.)

Duration with repeats: 1:20
