Sonata Allegro Exposition in C major, JS 179b
Romantic Sonata Piano solo ~4 min
In brief

This sonata exposition in C major has a brisk, contrasting character: poised main themes are set against more agitated accompanying figures, requiring clarity and steady rhythmic drive. You will face specific challenges in Analyse harmonique (3.6/5) — you must quickly spot shifting harmonic progressions to shape the phrase contours — and in Pédale de sustain (3.1/5), since pedal timing needs to be precise to prevent voice blurring during key changes. The piece belongs to the Romantic period and functions as the sonata-form exposition that establishes the movement's thematic and harmonic material. I do not suggest a reference interpretation here because I am not confident of a single clearly identified recording for this exact work.

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.
