III. Allegro assai

Wolfgang Amadeus Mozart · 1784 · C minor · 320 bars · 322 chords analysed

Mozart's dark C-minor sonata (1784); its drama looks ahead to Beethoven.

Mozart's 18 piano sonatas span his career, from Munich in 1775 to Vienna in 1789. Most have three movements — fast, slow, fast — and the first movement is usually in sonata form: two contrasting themes, a development that travels through other keys, and a return home.
