These Mandolin duet arrangements of the music of J. S. Bach are drawn from several sources. Most are arrangements of Keyboard pieces from The Anna Magdalena Notebook, English and French Suites, Two-Part Inventions, and some miscellaneous Keyboard pieces. Some of these are duet arrangements of music originally intended for solo Violin or Lute. The duets range in difficulty from easy to advanced. While these are arrangements for two Mandolins, any two concert pitch instruments can play them.
