Mozart’s Clarinet Concerto is a central work in the clarinet literature and a benchmark for every clarinettist. Mozart completed it two months before his death; it was the last solo concerto he wrote. He dedicated the composition to his friend, the clarinettist Anton Stadler, who was known for his expressive tone and who took the concerto on tour in the years that followed.

This single edition of the slow movement from Mozart's Clarinet Concerto has been issued as part of a series of popular works from the Bärenreiter catalogue celebrating the 100th anniversary of the publishing house. It is an excerpt from the piano reduction of the complete concerto (BA04773-90) which is based on the Urtext of the “New Mozart Edition”. The Adagio in ABA song form has been quoted many times, for example in the popular film "Out of Africa".
