Premiere
The work followed by some years the series of highly successful concertos Mozart wrote for his own concerts, and by the time of its premiere Mozart was no longer so prominent a performer on the public stage. The concerto may have been first performed at a concert on 4 March 1791 in Jahn's Hall by Mozart and by a clarinetist Joseph Bähr. If so, this was Mozart's last appearance in a public concert, as he took ill in September 1791 and died on 5 December 1791. Another possibility is that it was premiered by Mozart's pupil Barbara Ployer on the occasion of a public concert at the Auersperg palace in January 1791.
