This arrangement came about thanks to a bright, high school bass clarinet student from Washington State, expressing his desire to play a concerto of some sort. Though the repertoire for the instrument has been quickly expanding in recent decades, the arranger thought what might suit him perfectly would be just to simply transcribe this Rondo movement of the Mozart Bassoon Concerto. 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. The solo part suits the range of the bass clarinet very well and an extended range instrument is not required.
