Sonata in A major K.331
Sonata Piano solo 7 min
In brief

This sonata projects a clear, playful character and an intimate conversation between the singing right hand and the accompanying textures, requiring crisp articulation and a sense of dialogue rather than broad drama. You will face, in particular, Dotted rhythms (4.4/5) which demand precise control of note lengths and clear separation between long and short values — a supple wrist and confident fingering so the short notes are not blurred — and Classical style (4.4/5) which requires detached articulation and highlighting inner voices, so careful dynamic control and left-hand legato are needed. The piece belongs to Mozart's piano sonata repertoire and occupies the place of a melodic, formally balanced work typical of his output for piano.

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.
