The second volume in this complete survey of Mozart's piano sonatas focuses on three works from around 1778. The Sonata in E flat major KV282 opens with an unusually slow first movement — a singing Adagio — before two lighter movements. The Sonata in G major KV283 is one of Mozart's most perfectly proportioned works, its three movements combining grace with an effortless sense of inevitability. The Sonata in D major KV284 is the most ambitious of the three, its finale a theme with twelve variations that shows Mozart already exploring the form with extraordinary variety and inventiveness.
