How in the world can a transformer convert the AC frequency? U.S. 60 Hz AC at 120 volts input equals 60 Hz output, no matter what the output voltage is. That's why ring generators are so blasted expensive since they include the necessary coils and capacitors to modify the frequency down to the 20-30 Hz frequency that traditional ringers respond to.

If you can build your own circuits, here's a nice 30 cycle ring generator with interrupted ringing: https://ourworld.compuserve.com/homepages/Bill_Bowden/page11.htm scroll down to "Telephone Ring Generator Using Small Power Transformer"

Okay, STUPID suggestion ----- :p
Why not E-Bay a Panasonic KXTA 624 then he would have his choice of the North American one long ring, the Euro "ring-ring", or what ever miscellanous ring combos he'd like. They are cheap, pick up the correct telephone set for the ringer tone desired, and away you go. :shrug:

cell phones have a ringer you can download free (at least Sprint) that is the old time (pots) ring.

Remember guys, this gentlemen is a percussionist, as in an orchestra. That means he HAS to 'keep the beat'. I defy you to make a called phone ring at 'just the right time'! John C

John,
What do you think? A foot pedaled control of a one-shot controlling a timed relay based ringer?

No, you're making it too complicated. My guess is he'd get along fine with a foot switch that could handle 90V 20-30 Htz @ 1/4 amp. Probably an old dictation transcription footswitch from a Harris Lanier or Code-A-Phone.
Explain your 'tag line', I guess I'm too old to get it! John C
