I have created several scores for accordion over the last few years, some of which have been requested on YouTube and other places.
This score was only written out by hand, and was a modified version of a piano score. The version available here is just a PDF scan of my edited score (link will download file). You can listen to and download my performance of this score here or watch it here.
