The first volume of Hanns Eisler's piano works contains the three sonatas and a variation cycle. Surprisingly, it is precisely the rebel among the Schoenberg pupils who left behind a complex piano oeuvre and, after the journeyman's piece – the Sonata op. 1 (1923)– he even accomplished a remarkable stylistic development. Among these works are two impressive works of exile, the Variations for Piano (1940) and the Sonata no. 3 (1943), which is considered as Eisler's most original and significant piano work. Since the first editions were quite unreliable, the Eisler Complete Edition presents the first authentic and correct musical text.
