The pitch is determined by the amount of pulses in a given time. If I send 60 pulses
per sec, I get 60 sparks per second giving me a 60 Hz tone close to a B that is rich
in harmonics and shall we say very high in in THD (total harmonic distortion).
:-) If I want to hear a middle C, I send about 261 pulses per sec. But you have to
remember that each pulse to the coil allows it to go through a ring up of its
resonate frequency. In this case 41kHz.
So I guess to answer the question, the note being playing is the "electronic
breakrate". There are other things going on here with the sound that I am still
learning about. This stuff about how your brain can create the fundamental frequency
s from some of its harmonics when the fundamental is missing? The brain is a
incredible signal processor.

Good Show!
I love singing Tesla coils, being a musician myself, it a bridge
between my two great passions. I wish I had the time/funds/know how to
build a few myself. How exactly do they work, does it just modulate the
"electronic breakrate", or is it fed pure RF which is chopped up into
auditory pieces? Is there anyway to change the tonal qualities of the
sound or only the pitch? I wish I could have been there to see it in
person. Thanks again.
Scott Bogard.
