Violin Sonata no. 28 in E flat major, K.380
Classical Sonata Violin and Piano
In brief

This sonata has a bright, conversational character with lyrical episodes where short exchanges between violin and piano shape breathing and phrasing, giving it a lively yet singing quality rather than heavy drama. Technically, watch the Legato d'archet (3.6/5): you must keep a seamless bow connection across bow changes and string crossings so phrases remain smooth, and use Analysis harmonique (3.6/5) to anticipate modulations and shape cadences by adjusting bow weight and placement. From the Classical period, it belongs to Mozart's set of violin-and-piano sonatas, marrying formal clarity with chamber-like dialogue. I do not give a reference recording here out of caution about precise attributions.

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.
