For nearly 200 years, the 371 four-part chorales (371 vierstimmige Choralgesange) of Johann Sebastian Bach have enjoyed popularity and usefulness in music education. This classic collection has been used in choral classrooms for years and is especially accessible because the chorales have been reordered from the easiest to most chromatically complex in a four volume set. The parts are presented in open score format, instead of the customary keyboard reduction, for easier reading for choral students, and all measures are numbered for convenient rehearsal. The entire collection is presented in a reproducible digital download format for economy and utility.
