Adagio and Rondo - and Robert Childs

One of Mozart's best-loved and most performed pieces is the lively 'Rondo Alla Turca' from the Piano Sonata in A minor, K331, written in Paris in 1778. In this arrangement the Rondo is preceded by a little-known adagio, K580a, which existed previously as a fragment scored for solo clarinet and three basset horns. This completed version of the adagio is in sonata form, its main theme closely resembling Mozart's famous motet Ave verum corpus.
