remembers Raymond Scott's CIRCLE MACHINE: ''A big
disc, and a rotating arm with a photo-cell at the end. There
was a series of lights on the circumference of the circle that
this arm would pass, and you could adjust the brightness of each
lightbulb. As this arm swung around, and the photocell was illuminated
and got darker, the different sounds would come on and.off.''

recalls Raymond Scott's CIRCLE MACHINE: ''An analog
waveform generator that was this crazy, whirling-dervish thing.
It had a ring of incandescent lamps, each with its own rheostat,
and a photo-electric cell on a spindle that twirled in a circle
above the.lights.''

SCOTT
demonstrated his CIRCLE MACHINE during a lecture: ''This
device is what I've named THE CIRCLE MACHINE. The intensity of
each light in this circle is individually adjustable. At the
tip of the arm there is a photo cell. This cell is a part of
an electronic sound generating system, so adjusted that the more
light the cell 'sees' the higher the pitch of the sound produced.
The cell also moves around in a circle at adjustable speeds.
One of the controls, above the circle of lights, changes the
pitch center of the complete cycle when required. As you will
notice, there are many variable functions possible. Here is a
demonstration of an electronic effect possible with THE CIRCLE.MACHINE:''

SCOTT
continued his demonstration of THE CIRCLE MACHINE:
''...Now I would like to demonstrate a practical use of THE
CIRCLE MACHINE. The problem: To create a sound that goes with
the sequence of a TV spot in which the storage battery is dying
because the electrolyte is rapidly evaporating, ending in a short
circuit. The following demonstration starts with a CIRCLE MACHINE
impression of a dying battery. To keep the sounds generic in
this commercial, THE CIRCLE MACHINE is also used in a punctuation
manner. Here is our Ford 'AutoLite Sta-Ful' battery.commercial:''
