Some years ago, when I more often played the clarinet myself, I put Aaron Copland’s clarinet concerto on my music stand. “For Benny Goodman,” it read on the top of the first page. What hasn’t really attracted my attention before, now distracted me from practicing the challenging cadenza: When, how, why was this piece created? I started reading and researching, and soon learned that Goodman commissioned Copland to write a concerto for him in 1947/48 for 2,000 US dollars.
