Variations on a Hungarian Melody, op. 21 no. 2

The Variations and Fugue on a Theme by Handel, Op. 24, is a work for solo piano written by Johannes Brahms in 1861. It consists of a set of twenty-five variations and a concluding fugue, all based on a theme from George Frideric Handel's Harpsichord Suite No. 1 in B♭ major, HWV 434. They are known as his Handel Variations.
The music writer Donald Tovey has ranked it among "the half-dozen greatest sets of variations ever written". Biographer Jan Swafford describes the Handel Variations as "perhaps the finest set of piano variations since Beethoven", adding, "Besides a masterful unfolding of ideas concluding with an exuberant fugue with a finish designed to bring down the house, the work is quintessentially Brahms in other ways: the filler of traditional forms with fresh energy and imagination; the historical eclectic able to start off with a gallant little tune of Handel's, Baroque ornaments and all, and integrate it seamlessly into his own voice, in a work of massive scope and dazzling variety."
The autograph manuscript of the work is preserved in the Library of Congress.
