Piano Sonata, H 350: I. Poco allegro
Modern Sonata Piano solo beta difficulty
In brief

The first movement unfolds with contained, driving energy, alternating percussive figures and arpeggiated chords that produce a keen tension rather than long, singing melodies. You will need to focus on Analysis harmonique (3.6/5): here that means identifying chordal progressions and modulatory passages to shape voice-leading and register balance so dissonances and resolutions remain clear. The Polyrhythm 2 against 3 (3.1/5) occurs in several sections, requiring precise hand independence and a steady internal subdivision so the rhythmic layers align without losing forward motion. From the modern period, this sonata sits within Martinů’s piano works and reflects his interest in rhythmic texture and thematic economy in his catalogue.
