In 2013 we published these joyful, moderately difficult duos in a version for bass viols. However, Couperin intended them in the same way for other bass instruments, which is why we are now following them up with a version in bass and tenor clef that is suitable for violoncellos and bassoons. Our practical edition follows today's demands for faithfulness to the original. There are no page turns within the movements, and each player receives a score.
