Clarinet Concerto K.622 (version for Bb Clarinet & Piano)
The Concerto for Clarinet and Orchestra was written in October 1791, about two months before Mozart's death, and destined for Anton Stadler, the famous clarinettist.
The first movement exists in a sketch in G major for Basset Horn and Orchestra composed towards the end of 1789.
This edition has been published in two versions: in the original in A for Clarinet in A, and in a transposed version in B-Flat for Clarinet in B-Flat, in order to comply with the popular request for that instrument.
Available here is the version for Clarinet in Bb, as arranged by Ernest Roth and revised by Frederick J. Thurston.
