(from Prose Collection, 1968-74) full score available at Frog Peak Music
Make sounds with stones, draw sounds out of stones, using a number of sizes
and kinds (and colors); for the most part discretely; sometimes in rapid
sequences. For the most part striking stones with stones, but also stones on
other surfaces (inside the open head of a drum, for instance) or other than
struck (bowed, for instance, or amplified). Do not break anything.
