Ferruccio Busoni composed the majority of his chamber music during the years 1878-90 at a time when he was fast emerging as a formidable pianist of the younger generation. Written in 1890, the First Violin Sonata is a strikingly assured work whose three-movement form and forcefulness of manner place it in the lineage of Austro-German Romanticism that the older composer was to disown. The Second Violin Sonata, composed during the summer of 1898, was considered by the composer to be his real �Op. 1� in the sense that he had found his true voice. With its intricate part-writing, harmonic finesse and unorthodox form, the Sonata anticipates Busoni�s full maturity. The Four Bagatelles, with their references to popular German melodies, indicate Busoni�s ability, even at an early age, to integrate differing styles and types of music into his own work.
