full_question: The finale of Anton Bruckner's Fifth Symphony combines sonata form with this musical form, beginning when the strings pick up a theme introduced by a clarinet. "Accende lumen sensibus" introduces one of these marking the climax of the first part of Mahler's Eighth Symphony. Mozart combined all five of his previously used themes into a partial one of these pieces concluding the "Jupiter" Symphony. Beethoven's Opus 133 is a piece of this type originally intended as the concluding movement of his B-flat major String Quartet No. 13. In a posthumously published collection, an unfinished piece of this type follows four canons and thirteen others identified as "Contrapuncti." For 10 points, name this type of composition with two or more voices, the Art of which titles a late masterpiece by Bach.
