Brought to England from Rome as a child prodigy, Clementi became a notable figure in the music world as pianist, composer, piano maker, music publisher and teacher. A sniping letter in which Mozart dismissed him as a “charlatan” appears motivated by jealousy; Beethoven, however, admired him and gave him publishing rights to all his music in Britain. As a composer Clementi is best known for his keyboard etudes, Gradus ad Parnassum; nevertheless, much of his other music was influential, fascinating and rewarding. Jean-Efflam Bavouzet’s dazzling recording The Beethoven Connection includes Clementi’s Sonata in A major, Op. 50 No. 1, in which the musical cross-fertilisation with that iconic figure is audible from the start.
