If you want ot get tunes together for mandolin the ABC format is useful.

Some ABC's have chords as well!

Look for a a great piece of software called ABCplay2.EXE written by a guy in New Zealand. The software allows you to play ABC files and select tunes you like.

Then turn the tunes into TAB (if you are a non music reader like me).

I've written an ABC to TAB converter if anyone want to try it.

Then play till your fingers get sore!
