Grand Concert Paraphrase on Happy Birthday, Op.22

Try the interactive tutorial, or download the Sheet music here: musescore.com/...
This is a concert fantasy based on the famous theme of Happy Birthday. I have composed this piece to challenge my ability to transform a single theme/motif in many different ways, and then weave them into a coherent piece.
I hope you guys like this piece, and please feel free to drop some comments!
