So far as I know this is MIDI ofer an arduino

Is this just a manifestation of "any electromechanical widget will
make a somewhat musical noise if you pulse it the right way?". ?In other words, would relays, motors, solenoids or
doorbells be just as
adequate to the task?
I don't know that you could get the same frequency range from
solenoids due to inertia (and perhaps the time it takes to create and
collapse such a large magnetic field). You certainly could take
random stepper motors and stepper drivers and reproduce the effect.
I suppose one could switch relays fast enough for some of the lower
notes, but I have to wonder how well relays would work at 500Hz and
above.
