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 work’s unusual source materials. Mozart’s 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.
