Musser's
Rhythm Machine
Donated by Perry and Nancy Preusch.

Clair Omar Musser designed and built his "Musser Maestro
Marimba Metron" as an accompaniment instrument to his solo
mallet performances. The instrument plays thirteen electronically-generated
"tempi figures" including ten standard dance rhythms
such as the bolero, waltz, rhumba, cha-cha, tango, samba, and
beguine. In addition to the ability to produce both electronic
metronome pulses and duple meters using five different drum
and cymbal beats, a wide range of individually activated percussion
instrument tones is also available.
The percussion tones, operated by pressing or striking the buttons,
include bass drum, two tom-toms, two temple blocks, woodblock,
claves, and maracas sounds, along with two real cymbals that
are mounted inside the case and struck by solenoid action. Nancy
Preusch recalls that Musser struck these buttons with his mallets,
causing noticeable abrasions to the painted wooden framework.
Musser personally used this instrument, commonly referred to
as his "Rhythm Machine," not only for performances,
but also for teaching in his studio at Northwestern University
and in his music room at Studio City, California. As it is built
with end frames of the same design as his Canterbury marimba,
it apparently dates from 1949-52, and was manufactured using
vacuum tube electronic technology from that era.
Musser's Rhythm Machine measures 18" wide,
34" deep, 32" tall (frame only), and 35" tall
(frame plus wheels). The upper platform panel where the buttons,
switches, and dials are located is 8" wide by 28"
long.
