Not with that attitude. :)
It can play one "note"... so just get yourself an array coils in a big
electric pipe organ.
Or a rotary spark gap with a variable speed drive
Or a triggered spark gap
Or an array of rotary spark gaps with different numbers of contacts
and/or speeds, using gears and belts to create harmonically related notes
Lest you think the latter is impractical, I believe it has been done.
It was called something like the telharmonium or tesla organ or
something.. early in 20th century.
(the telharmonium didn't use HV tesla coils.. but who's to say that
someone didn't modify it for such.. I'm sure I saw a picture somewhere)
use semiconductors? While I'm sure Nikola would approve of modern
technology to do this, there's a certain appeal in using an architecture
that is 100 years old (albeit with modern materials.. I've no desire to
fabricate my own gutta percha insulation, etc.)
And, in fact, you could probably use multiple capacitors and inductors
in the primary on the same secondary. The typical "conduction period" is
a few cycles at, say, 300kHz. So, while primary tank #1 is firing at
440 Hz, primary tank #2 is firing at 350 Hz, and you have a spark driven
dial tone generator!
It would be an interesting spice model: 1 secondary, 3 primaries, at
break rates in the ratio of 4:5:6 and you'll get a Major Triad, just
like your Mac when it starts up.
