Piano Sonata no. 1, S. 87: IIa. Allegro moderato - Andante
Modern Sonata Piano solo beta difficulty
In brief

This movement balances contained briskness with lyrical relief, featuring irregular accents that give a sense of intertwined but clear musical argument. You will face specifically Analysis harmonique (3.6/5): here you must identify and convey unstable harmonic progressions by shaping chord colors and voicings, working the hand to bring out pivot tones that shift tonal focus; and Polyrhythmie 2 contre 3 (3.1/5), which requires precise finger and wrist independence to sustain a ternary pulse against a binary one without disrupting the musical flow. The piece belongs to the modern period and is one of the composer's piano sonata movements where he explores the layering of styles and textures within sonata form. I do not provide a recommended recording because I am not fully certain of a definitive reference for this specific movement.
