Clarinet Concerto
The Clarinet Concerto in A Major, K. 622 is a musical work composed by Wolfgang Amadeus Mozart in the late 18th century. 

In 2372, Harry Kim practiced the first movement of the piece ("Allegro") on his clarinet in his quarters when he was interrupted by Tom Paris, who came to the ensign's quarters to tell him about his love for Kes. ()
