Sir Donald Tovey (1875–1940), long hailed as one of the finest writers on music in English, saw himself primarily as a composer. His occasionally turbulent friendship with Pau Casals was the spur for a monumental concerto and one of three sonatas: for solo cello, two cellos and cello with piano. The cello was the ideal instrument for Tovey’s Brahmsian musical language, with its long, singing lines unfolding in effortless counterpoint – though the huge passacaglia that ends the solo sonata also demands a virtuoso technique. The brief Bach arrangement recorded here for the first time arose when the twelve-year-old Tovey added a cello line to one of Bach’s best-known preludes, originally for lute.
