Cello Concerto in A minor

Schubert wrote no cello concerto. This one was assembled in the twentieth century by the Catalan cellist Gaspar Cassadó (1897–1966), a pupil of Casals who produced a series of such compilations, and its principal source is the Sonata in A minor D 821 of 1824 — the piece Schubert wrote for the arpeggione, a bowed guitar that had been invented the year before and was obsolete within a decade. Cassadó redistributed the material into concerto form and orchestrated it, adding transitions of his own. Cellists have kept it in circulation as a way of playing familiar Schubert with an orchestra.
