Piano Sonata no. 3 in C major, op. 25
Modern Sonata Piano solo 7 min
In brief

The C major Sonata unfolds with a cinematic brightness, alternating lyrical episodes and virtuosic outbursts with dramatic conversational writing between the hands. Technically, Connaissance des formes (3.6/5) is crucial here: you must identify sections clearly, shape transitions and phrase repeats so the form remains audible through the virtuosity, and Polyrhythmie 2 contre 3 (3.1/5) requires precise hand independence to keep a steady pulse while superimposing cross-rhythms. The work belongs to the composer's modern period and is part of his solo piano output, showing a blend of late-romantic language with more modern inflections within his catalogue.

Where this work sits
050100

Most works cluster between 45 and 65: a small score gap often marks a real step. The highlighted bar shows this work among those for the same instrument.

The MusicCoach difficulty measures a work's overall demands (technique, reading, stamina) on a shared 0-100 scale, consolidated from editorial and pedagogical reference points (Henle, exam syllabuses, curation) and our own analyses. It measures neither musical value nor the practice time YOU will need: two musicians of the same level can experience the same work very differently depending on their strengths (hands used to octaves, quick sight-reading…). The confidence reflects how many reference points sit behind the score and how well they agree — a lightly documented score is flagged “to validate”. For a truly personal bearing, the diagnostic and your space compare each work to YOUR estimated level, which the score alone cannot do.

Does this rating look right to you?

This rating is computed automatically from heterogeneous sources. It gets things wrong, sometimes badly. If you know this work, your answer is worth more than our computation: it tells us which ratings to review.
