This is a very hard piece to play. 3 people on the piano and maybe 1 or 2 people on the violin will be enough. I guess you can call this an "impossible piece". For the most hectic parts, go to measures 50-57 and measures 73-80. It starts off simple, and gradually adds more and more melodies until it's too much for a set of hands to handle. I hope you enjoy it! (It's an original piece).
