Violin Sonata in B-flat Major, K. 15
Sonata Violin and Piano
In brief

This B-flat major sonata by Mozart feels bright and playful, driven by quick exchanges between violin and piano rather than deep dramatic contrasts. Technically, pay attention to Technique générale (2.5/5): expect precise left‑hand position changes and steady bow control to keep articulation clean, and to Phrasing (2.5/5) which requires shaping short melodic lines through subtle changes of attack and emphasis rather than large gestures. It is a youthful work in Mozart's output, placed outside the more mature experimental phase of his career and generally considered among his early violin-and-piano sonatas. I do not provide a recommended recording here, being cautious about naming a definitive interpretation for this particular piece.

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.
