Piano Sonata (Allegro moderato) c minor R. 354 (19)
Sonata Piano solo
In brief

This C minor sonata feels driven and restrained: short, motoric motifs that ask for controlled energy rather than broad virtuosity, and a compact touch in the lower registers. You will need to focus on Independence of the hands (2.5/5) — here that means keeping a steady accompanying pattern while bringing out the melodic line without one overpowering the other — and Phrasing (2.5/5), which requires shaping small musical units so responses and sequences remain clear; Dynamics (2.5/5) are also useful to shape the piece but at a moderate level. It belongs to Kuhnau’s keyboard output and reflects the late-Baroque keyboard sonata tradition, showing the shift toward more pre-classical forms.

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.
