The concerto was created for the clarinetist Anton Stadler, a close friend of Mozart’s, known for his virtuosity. The close relationship between composer and musician is palpable throughout the work, especially in the second movement, whose lyrical Adagio belongs to the most moving moments in all of classical music. Mozart’s Clarinet Concerto remains a staple in the repertoire of clarinetists worldwide and is often regarded as the pinnacle of the clarinet repertoire. It embodies a perfect harmony between soloist and orchestra, with the clarinet acting alternately as leader and accompanist.
