Sonata in A major, K.209, L.428
Baroque Sonata Piano solo ~4 min
In brief

This A major sonata by Scarlatti feels bright and nimble yet pointed, with lively exchanges and sharp rhythmic punctuation that require a crisp attack to bring out the dialogic responses. Technically, you will need to work on Analysis harmonique (3.6/5) to spot cadences and quick modulations so you can shape phrases according to harmonic shifts, and on Ornements baroque (3.1/5), which demand precise execution of embellishments on the keyboard through controlled finger articulation and a supple wrist so trills and mordents remain clear and expressive. As a baroque keyboard sonata, it belongs to Scarlatti's large corpus of single-movement sonatas that explore terse contrasts and keyboard idioms. I do not provide a recommended recording here, out of caution about attributing specific reference performances to this particular 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.
