The most beautiful and significant clarinet concerto in the history of music is now appearing in a Henle urtext edition. The piano reduction is accompanied by two separate parts: an urtext edition of the original clarinet part as found in the early prints, and a reconstruction for basset clarinet, the instrument for which the work was originally written. The editor, Henrik Wiese, provides a preface and commentary with an in-depth discussion of the workÆs unusual source materials. MozartÆs concerto has become the indispensable audition piece. As a special bonus, this edition also includes the text of the autograph fragment for basset horn in G.
