Mozart's piano trios have been available in an established Henle edition in parts for many years. They have now been extensively revised by the editor and include the latest musicological findings. In particular, the autograph scores from the Library of the Jagiellonian University of Cracow, which were not accessible for many years, form the basis of this revision with its extensive commentary. On the occasion of this new edition, Henle is proud to present a study edition of the piano trios for the first time.
