La Bergius in B flat major, H.90, Wq.117, no. 20
Classical Piano solo ~2 min
In brief

This piece is brisk and playful, with short replies and occasional ornamented outbursts that require nimbleness and attention to inner contrasts rather than broad, sustained lyricism. Technically you will need to use your Connaissance des formes (3.1/5) to clearly shape repeats, transitions and small modulatory episodes, and focus on Phrasing (2.5/5) by refining articulation of short phrases — measured wrist motions and quick releases between motifs to maintain clarity and coherence. The work belongs to the Classical period and reflects C. P. E. Bach’s keyboard writing at the crossroads between late Baroque sensibilities and emerging Classical expressiveness.

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.
