The Bassoon Concerto in B-flat major, K. 191/186e, is a bassoon concerto written in 1774 by Wolfgang Amadeus Mozart. It is the most often performed and studied piece in the entire bassoon repertory. Nearly all professional bassoonists will perform the piece at some stage in their career, and it is probably the most commonly requested piece in orchestral auditions – it is usually requested that the player perform excerpts from the concerto's first two movements in every audition.
