Martin Rummel - Editor Barenreiter's justly-praised musical scholarship and graphics skills are here applied to the relatively humble pedagogical material of composer Jean-Louis Duport, his older brother Jean-Pierre, and Jean-Pierre's teacher Martin Berteau.

In this edition, Barenreiter restores the long-unused second cello accompagnato part with the same degree of care and scholarship characteristic of everything else the publisher does. All page turns are solved, clear graphics emerge as do bar numbers, and questionable notes are flagged.
