Jim,
All of the VFDs that I have worked with have three phase outputs.
Unless you are driving a three phase transformer, I do not expect that
one would work well, if at all. I have had industrial synchronous
motor drivers (which are a sort of sophisticated VFD) fail
catastrophically when one of the three output phase leads became
disconnected from the motor.
In any event, VFDs are packed with sensitive internal electronics,
intended for driving relatively quiet (electrically speaking) three
phase motors. TCs are electrically very noisy devices, with large
spikes coming back into the line through the power transformers. I
would not expect an ordinary VFD to last long in TC duty, even if you
can get it to work.
Better be sure you can afford to pay full retail for the loaner VFD if
you happen to let all the magic smoke out of it.
Most of the musical coils that I've encountered are of the solid state
drive versions. You could use your current secondary, and probably
your toroid, but the SSTCs I've seen usually have smaller, more
closely coupled primaries than typical disruptive TCs. Many have only
a single turn primary.
If you really want musical output, heading in this direction is
probably going to be the easiest path to what you want.
Easternvoltageresearch.com is one seller which offers proven kits of
SSTC driver boards in various configurations. (no connection to seller)

Yes sir it is a static spark gap.
I will see if the electrical supply house will loan me a 540 watt vfd.
Thanks.
