Piano Sonata in A flat major, op. 92
Romantic Sonata Piano solo ~20 min
In brief

This A-flat major sonata feels bright and poised, alternating lyrical cantabile sections with sparkling passagework that requires maintaining rhythmic clarity amid ornamentation. Technically, the Analysis harmonique (3.6/5) will require you to quickly map harmonic shifts and inner voices so you can balance accompaniment and melody; the Sustain pedal (Pédale de sustain, 3.1/5) requires precise, often partial pedaling to prevent blurring in wide chords. From a factual viewpoint, the work belongs to the early Romantic period of the composer and occupies a transitional place in his output between classical models and more virtuosic gestures.

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.
