THE
VIBULUM FAMILY
(MOTOTONES)
The
first vibulum was an eight-inch vibrator hung to swing as a pendulum
above a magnetic bass pickup. A low-voltage motor is "picked
up" the same way a vibrating string is picked up because it
is oscillating metal within a magnetic feild.
This "mototonous"
effect has been used in three basic configurations.
1. VIbuilum
- pendular motion
2. Vibrokick - back and forth motion, using a kickdrum pedal as
a chassis.
3. Vibrowheel - rotary motion, using a small, heavy flywheelas a
chassis. As the wheel speed increases, centrifical force slows the
motors. At very high speeds the motors stop, but the wheel spins
fast enough over the pickups to create a new tone.
