Whether the work is in one volume or four, the fact remains that Banjocircus can learn something useful FOR FREE by using the good old Public Library.

As for notation, I use Noteworthy Composer, which is very reasonably priced and produces very nice printed music. My friends and I have been playing multi-part music made with Noteworthy for years.

Some posts say that there are free programs which will print out MIDI's for you, but over the years I have learned that sounds can have strange effects on a computer. I prefer to deal with an established firm with a street address and a staff. Why risk a computer to save $50?
