Ah, yes, the mystical Cupcake Flute. Immortalized in Mozart's famous opera of the same name... oh, wait, that was the Magic Flute. My bad.
In any case, we have some great flute music for Cupcakes, thanks to fan Pegaspaniel. Check out the sheet music here. Hopefully the flute players out there will enjoy! You can find Pegaspaniel on Youtube.
Thanks for sharing your resource, Pegaspaniel!
