Difficulty estimate by MusicCoach on a scale of 1 to 100.
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.
One rarely plays the whole work: each movement has its own level — often very different from the opus's overall score.
Each suggestion combines difficulty gap, risk, confidence and skill overlap. The first two cards in each column are the most useful pedagogically.

The first movement of the Sonata in C major K.330 has a bright, conversational character built from singing phrases and quick replies that require clear articulation and a steady sense of rhythmic relief. Technically, the skill Connaissance des formes (3.6/5) will require you to identify and shape the sections (exposition, development, recapitulation) to plan breaths and repeats, and Analyse harmonique (3.6/5) asks you to anticipate modulations and chord progressions so you can balance the voices and prepare resolutions through precise adjustment of touch and hand weight. This sonata is part of Mozart's piano repertoire and sits among his keyboard works that exemplify his Classical treatment of sonata form. I am not giving a reference recording here because I prefer not to cite a name unless I am certain of it.
