Published posthumously, Schubert’s sunny three-movement Sonatine No. 1 was part of a three-strong set composed in 1816, and its only major-keyed work. Beethoven’s ‘Kreutzer’ Sonata had higher-profile beginnings. Written for the 1803 Vienna debut of violin virtuoso George Polgreen Bridgetower, with Beethoven himself at the piano, its concerto-like writing for both instruments clearly plays to a premiere starring not one but two international soloists, even if a quarrel then meant the final dedication went to French star soloist, Rodolphe Kreutzer. Its warm chordal opening is, strikingly, for violin alone. The piano swiftly follows, as does A minor fire and virtuosity. A central Andante cast as a theme and variations brings calm, before a whirling tarantella-rhythm Presto finale.
