In 1801, these duets were published by Sieber fils, Paris. Naturally, we have respected the original text, based on the edition deposited at the Bibliothèque Nationale, Département Musique. We have confined ourselves to correcting a few obvious engraving and movement errors. The first edition was published in separate parts. We have combined the two clarinets on the same score to facilitate reading, both musically and pedagogically.
