My Harmonica Songs

Write your favorite songs and play them wherever you go using your harmonica. You can add positive numbers which mean you have to blow into the specified hole and negative numbers which mean you have to draw from the specified hole. For example:
4 means blow into hole 4
-5 means draw from hole 5

This app was made to help one improve his harmonica skills and to have his composed songs with him at all time.

I will keep it updated with new features and I appreciate any feedback or ideas you may have.
