The 1848 Shaker song “Simple Gifts” rose to prominence after American composer Aaron Copland borrowed its melody for his composition Appalachian Spring, which he wrote to accompany a ballet choreographed by Martha Graham. Cellist Yo-Yo Ma covered the tune on his 2001 album Classic Yo-Yo with vocalist Alison Krauss.
The track begins with a cello introduction in Bb and shifts down a fifth to Eb when Krauss enters at 0:46.
