Sonata for Piano no. 9 in B major, op. 147, D. 575: I. Allegro ma non troppo
Sonata Piano solo beta difficulty
In brief

The Allegro ma non troppo opens with a lyrical yet buoyant character, alternating bright rhythmic figures with inward, song-like themes that require keeping the lines clear while retaining a gentle poetic flow. Technically, Connaissance des formes (3.6/5) is crucial: you must identify and shape repeats, transitions and recapitulations so phrases and cadences feel logical, which involves clear changes of intention at structural points; Tempo rubato (3.1/5) is used to model the principal voice against often steady accompaniment, requiring wrist control and hand independence to stretch or compress the local pulse without breaking the underlying rhythmic framework. This sonata belongs to Schubert's body of piano sonatas and shows his habit of placing lyrical melody into reworked classical forms. I do not provide a performance reference because I am not 100% certain of a single recording widely accepted as the definitive reference for this specific movement.
