A Nocturne is a form of musical expression inspired by or used to evoke characteristics of the night. Hence its etymology in the term which is from the French language, meaning "nocturnal." When used in popular reference, possibly as "The Nocturne," the term is almost exclusively reserved for that of Chopin's, Opus 15 No. 2 in F sharp major.

In episode 309 of The Muppet Show, an entire portion of the show is dedicated to a concert by Liberace for the Birds on the show. One of the pieces he plays is "Nocturne No. 5 in F-sharp Major (Op. 15, no. 2)" by Chopin, which he figured would please Sam the Eagle; it even garnered cheers from Statler and Waldorf.
