Daniel Barenboim performing the Beethoven piano sonata no. 31, opus 110 in A flat major. Composed in 1821, it is the central piano sonata in the group of three opp. 109–111 which he wrote between 1820 and 1822, and the thirty-first of his published piano sonatas.
The sonata is in three movements. The moderato first movement in sonata form, marked con amabilità, is followed by a fast scherzo. The finale comprises a slow recitative and arioso dolente, a fugue, a return of the arioso lament, and a second fugue that builds to an affirmative conclusion.
