Keyboard Sonata in A major, Wq. 89, no. 3, H.527
Classical Sonata Piano solo ~8 min
In brief

This A major sonata presents crisp, contrasting episodes—sprightly, dance-like passages alternating with more reflective interludes—requiring rhythmic precision and swift shifts of character. Technically, you will need to focus on Analysis harmonique (3.6/5) by mapping the modulations and chord progressions so you can adjust touch and voicing accordingly, and on Phrasing (2.5/5) to shape the short, conversational phrases with varied attacks and controlled legato that bring out their responses. The work sits within C.P.E. Bach’s classical keyboard output, showing the link between the empfindsamer style and emerging classical sonata principles in 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.
