Absolutely the same reaction from me, Art! I finally saw that movie last year after hearing so much about it.

I read this thread several days ago and realized that no one addressed my particular problem. Intentional tremor (a tremor at the end of a long muscle movement - makes it hard to change hand positions on the piano quickly - a hammered dulcimer would be impossible!) And also the stiffness when under pressure - making a lap dulcimer hard to perform.

I have good "sequential" fingering, so the whistle might be possible, but oooooooh, does that take a lot of breath!

I just enjoy playing simple piano arrangements and composing midi files.
