Not too easy finding music for the plectrum (4 string) banjo. I was looking for ragtime plectrum banjo music, and here it was. The four numbers by Scott Joplin are worth the book price. It also includes a dozen or so more by lesser sources. A great find. By the way, its all in standard musical notation, so not for the rank beginner. Mel Bay presents Ragtime Banjo For Tenor or Plectrum Banjo (Archive Edition)
As a previous reviewer said, it's hard to find print music for tenor banjo, so it has some value. However, I wish the publishers had included more popular tunes from the Ragtime era instead of Roy Smeck originals. Nothing against Mr. Smeck's compositions, but I would prefer to invest time in learning tunes that are more widely recognized.
