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

The III. Adagio. Poco allegro projects a dream-like yet tense mood: suspended slow lines alternate with sudden rhythmic outbursts, producing a feeling of instability where calm can turn into agitation. You will be especially challenged by Analysis harmonique (3.6/5) — here that means following shifting modulations and subtle dissonances while adjusting inner-voice balance and pedaling to keep harmonic progressions clear — and by Polyrhythmie 2 contre 3 (3.1/5), which requires precise subdivision between the hands and thumb control with independent phrasing so the interlocking rhythms remain distinct without smothering the melody. This sonata belongs to Martinů's modern-period piano repertoire and exemplifies his exploration of harmonic color and rhythmic complexity for solo piano.
