In an earlier post I said:
Just wanted to add how I got interested in theremins.
When I watched Peter Pringle play "Somewhere, Over the Rainbow", I was "hooked"!
Also watching Thomas Grillo playing Burns B3-deluxe, I decided that might be a good place to start.
After playing a B3-deluxe for about a year, I decided to try to play along with Peter Pringle's rendition of Somewhere Over the Rainbow.
The results: I reinforced my earlier conclusion that the theremin has a long learning curve. What I do compared to Peter Pringle is just hit a few of the notes about right. To paraphrase an early rock and roll singer, what I do is make a noise--some might be charitable and call it music.
Another result: Trying to play along with some of the good players, I started noticing some of nuances of interpretation in their playing. This appears to be a good way to improve my appreciation in listening to others play.
