These new English translations of the texts of J. S. Bach's vocal music are based on the historical language and theology of Bach's time. (See "About the translations" at the link above.) They are made freely available for concert programs, recording notes, and course materials. (See "Using these translations.")

This is an ongoing project, and translations of other cantatas will be added as they are completed.
