Violin Sonata no. 16 in B flat major, K.31
Classical Sonata Violin and Piano
In brief

This B-flat major sonata has a bright, salon-like clarity and sprightly character: short movements, singing themes and rhythmic accents that call for precise articulation rather than sustained emoting. Technical challenges: Bow legato (3.6/5) — work on seamless bow changes with small, controlled strokes and even bow distribution to preserve line without over-emphasizing tone; Knowledge of forms (3.6/5) — you must clearly map phrases, repeats and episodes so dynamics and breathing points shape a coherent overall structure. From the Classical period, it belongs to the composer's body of violin-and-piano sonatas and exemplifies the elegance and clarity of the genre. I do not give a recommended recording here, out of caution about accurately attributing specific interpretations.

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.
