Sonata in B flat major, K.550, L.S42
Baroque Sonata Piano solo ~4 min
In brief

This B-flat major sonata feels sprightly and dance-like, built from short motifs and rhythmic breaks that require crisp articulation and a steady pulse rather than broad orchestral shading. You will specifically work on the skill “Ornaments baroque (3.1/5)”: here that means executing mordents and short trills cleanly with compact fingering and controlled wrist release so the embellishments stay clear without blurring the line; “Knowledge of forms (3.6/5)” is also required because the sonata follows a binary form with repeats where you must shape and balance the two sections through phrasing and subtle dynamic choices. A baroque keyboard piece, it belongs to Scarlatti’s large group of keyboard sonatas and exemplifies his combination of virtuosity and melodic invention within a concise form.

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.
