ave you ever wanted to make music just by
waving your hand? Well that is just what you are
going to be doing. How does this magic work? Well,
t
he tones change based upon the amount of light
that gets to the CdS cell. With a bright light the tone
is higher but, if you cover the CdS with your hand,
the sound gets lower.
Since the early days of vacuum-tube circuitry, this
method of creating musical sound has been used.
Leon Theremin was the inventor of this type of
instrument, thus the instrument has been named
the Theremin in his honor.
After the wiring has been completed press the key
and then wave your hand over the CdS cell. You will
soon be able to play music with this magical
electronic instrument after just a bit of practice. Most
importantly HAVE FUN!
