In writing this excellent set of variations on a theme for Orchestra, Brahms actually got it a bit wrong. The theme (an old tune named the 'Saint Anthony Chorale') is not really by Haydn, but was used by him. Whateveritsparentage, this march-like tune, dignified but with a twinkle in its eye, is an outstanding basis for variations. After the opening statement of the theme, there are nine variations, easily distinguished by the listener, whowillbe amused and impressed by the variety of techniques Brahms uses to give each one its own special mood - whether romantic, brisk or very lively! The last section gets more passionate as Brahms uses the original theme as abassline and works out mini-variations over it. At the end, the original theme comes back in a grand statement. This is a Piano arrangement of the orchestral work.
