Like the Italian Concerto for solo harpsichord (BWV 971), the Concerto a due cembali is Bach’s only concerto expressly written for two unaccompanied harpsichords. He probably composed it in Leipzig some time around 1733; later he provided an alternative version with a string ripieno in the first and third movements. The original version for two unaccompanied harpsichords appeared for the first time as a scholarly-critical edition in the “New Bach Edition”. It forms the basis of our new performing edition, which draws on the latest findings of scholarship to provide an ideal foundation for the most discerning musicians.
