For nothing more than my personal amusement, and my agenda to make banjo music as accessible as possible, I have been pulling all of the banjo music out of the Crescendo magazines and adding them to the Internet Archive.
After going through the entire run I ended up with about 215 pieces, give or take. Many were published in both C and A notation.
This runs the gamut from 1880s waltzes and schottisches up to mid 1920s "jazz" arranged for both fingers and plectrum (though after playing them both ways I would say they were more plectrum than fingers solos).
Lots of great, and not so great, pieces here with much unexplored territory.
