Sonate K.545 « Facile » : III. Rondo
Sonata Piano solo
In brief

The third movement is bright and lively, with a recurring brisk refrain and light episodes that require clean articulation to preserve the dance-like clarity of the music. Key technical points: Staccato (4.6/5) here requires precise finger release and a controlled wrist action to produce short yet sonorous attacks, and Scales and arpeggios (4.6/5) demand consistent fingering and smooth hand transfers to keep rapid passages even. The piece belongs to the Classical style and sits among Mozart's piano sonatas, often treated as both a didactic and concert movement because of its clear formal design. I do not provide a reference interpretation to avoid offering a possibly incorrect attribution.

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.
