Snider, Robert - Timbre Variations

Timbre Variations is an exploration of the different sounds of the percussion family. Groups of instruments include: tuned idiophones (keyboard percussion), struck indefinite pitch (triangle, wood block...), shaken or scraped idiophones (maracas, sand blocks...), and membranophones (timpani, tom toms...). The variations are set up by instrument sounds, while the basic form and rhythm remain constant in each variation.
