The "St. Anthony Chorale Variations" were originally called "Variations on a Theme by Haydn" but it is now known that Haydn didn't compose the Theme. Brahms created 2 versions of his set of variations: one for Two Pianos (Op.56b) and one for Orchestra (Op.56a). This music is based on the Two Piano version but adapted for Piano Solo by Jim Paterson. Here is the Piano Sheet Music. See below for video, mp3, midi and score.
Other versions of this theme on mfiles include: Orchestra (Brahm's Op.56a version), Two Pianos (Brahm's Op.56b version), and Trio (illustrated on Oboe, Clarinet & Bassoon, but with alternative parts suitable for other instruments).
