Sonata in D major, K.436, L.109
Baroque Sonata Piano solo ~4 min
In brief

This sonata projects a bright, playful energy, built on quick exchanges and insistent motifs that feel more like a nervous dance than extended lyricism. You will need to work on Ornements baroque (3.1/5) by fitting small grace notes and rapid embellishments into the melodic line without breaking the flow, and on Lecture clé de fa (3.1/5), which here requires careful left-hand reading to keep the bass singing and to manage detached leaps. As a Baroque piece, it belongs to Scarlatti’s large group of short, virtuosic keyboard sonatas intended for harpsichord or early piano. I will not name a reference recording unless I can be certain of it.

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.
