What began as an arrangement of this movement for a budding high school bass clarinet soloist has evolved into a full arrangement for soloist accompanied by clarinet choir. Naturally, even though the original intent of this arrangement is for a bass clarinetist to be feature, the solo part could also be successfully performed by a bassoon, euphonium, or even a trombone. Written when Mozart was only 18 years old, this concerto is a cornerstone in the repertoire, and bassoonists are typically expected to play at least part of it in any orchestral audition.
