Sonata in B flat major, K.155, L.197
Baroque Sonata Piano solo ~6 min
In brief

This B-flat major sonata has a playful, brisk character built on detached figures and quick echoes that require steady rhythmic precision rather than expansive lyricism. You will need to focus on Connaissance des formes (3.6/5) to clearly shape and balance the A and B sections and their repeats — making decisive phrasing and dynamic choices at each return — and on Ornements baroque (3.1/5) where mordents and small trills call for fast fingers and precise wrist pivots to keep them crisp without disrupting the flow. A Baroque keyboard sonata, it belongs to Scarlatti's many short sonatas that investigate keyboard techniques through concise motifs and sharp contrasts. I have not suggested a reference recording because I am not fully confident of a single universally recognized interpretation for this specific sonata.

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.
