Nice!

How does one control the frequency of the sound?

Because solid-state coil drivers are limited to "on-off" modulation, the sound produced consists of square-like waveforms rather than sinusoidal (though simple chords are possible).

So if I understand correctly, the sound is produced by turning the spark on and off in the desired frequency.

Somewhat similar to floppy drive music (where stepper motors are turned with the desired frequency, again producing square waves).

It would be nice, though, to investigate ways to make sounds that are not boring square waves.
