Teach every pupil to look after and offer protection to his or her clarinet. It is an instrument, not a toy, and merits good cure and admire. If students consider they're in ownership of a precious object, they'll learn to value it, and they'll value the work they do with it all the more. What may have motivated Mozart into finishing the deserted basset horn concerto for Stadler and his basset clarinet, was his adventure to Prague for the superior of La Clemenza di Tito. One of his vacationing partners was his pupil Süssmayr, who discovered that he was writing a basset clarinet concerto for Stadler. Mozart couldn't allow himself to be outdone. The concerto was written in Vienna a while between the top of September and the beginning of October 1791. The accomplished score was sent off to Stadler in Bohemia and it bought its first performance at Stadler’s benefit concert in the Prague Theatre on October 16, 1791. Seven weeks later, Mozart was dead. Even in Mozart's day, the basset clarinet was a rare, custom made instrument, so when the piece was posted posthumously, a new edition was organized with the low notes transposed to usual range. This has proven a tricky choice, as the autograph no longer exists, having been pawned by Stadler, and until the mid 20th century musicologists did not know that the one edition of the concerto written by Mozart's hand had not been heard since Stadler's lifetime.
