I was thinking mozart or hadyn , maybe even beehtoven. My knowledge though on hadyn and mozart is very little. I swear I know that tune(maybe J.Lee will recognize)I don't know.
They are more than alright right, they are fantastic. You keep everything pretty well knitted up.(like monkeys on bananas)(slightly difficult to explain that)
If the piece comes up, you'll be the first person I'll tell
P.S. This deserves a concerto name(no variation) plus you plann'n on posting the second and third movements?
