Premiere
The concerto was given its premiere by Stadler in Prague on October 16, 1791. Reception of his performance was generally positive. The Berlin Musikalisches Wochenblatt noted in January 1792, "Herr Stadeler, a clarinettist from Vienna. A man of great talent and recognised as such at court... His playing is brilliant and bears witness to his assurance." There was some disagreement on the value of Stadler's extension; some even faulted Mozart for writing for the extended instrument.
