Piano Sonata b minor Wq 65,13
Sonata Piano solo
In brief

This B minor sonata unfolds an inward tension and sharp contrasts, alternating crisp gestures with singing episodes that require careful control of relief and articulation to shape the musical argument. Technically, you will need to focus on Independence of the hands (2.5/5) — here that means coordinating differing rhythmic patterns and voices without blurring the principal line — and Legato (2.5/5), i.e. maintaining even connections in the cantabile passages while preparing shifts of accent. The piece belongs to C. P. E. Bach's body of keyboard sonatas and reflects his taste for expressive contrast in keyboard writing. I have not listed a reference recording without being certain; I can suggest recorded interpretations after checking them.

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.
