Adapted to marimba from a keyboard transcription of J.S. Bach's Sonata in A Minor BWV 1003 for violin, Bartlett's minor adjustments make this an easily accessible addition to the repertoire. A 5.0 octave instrument is required.

For solo percussion and computer-generated sounds, this piece explores a variety of timbres, meters, and rhythmic juxtapositions with a fairly modest set-up of 3 metallic membranes, roto-toms, 2 toms, bongos, a concert pedal bass drum, and chuan bo.
