From the developer:
BarFly is an integrated text editor/player/viewer for abc music files.
What's abc? abc is a system of notation for music which uses ordinary ASCII text to represent the symbols which you would normally write on music manuscript. It is simple, human-readable, and if you can touch type it is much faster to enter abc at the keyboard than it is to use a graphical music program to place notes on a staff using the mouse.
