Violin Sonata no. 25 in F major, K.377
Classical Sonata Violin and Piano
In brief

Mozart here unfolds a clear, pastoral brightness: the piece moves between singing, answer-like phrases and more dance-like episodes that require playful energy without losing lightness. You will specifically face Vibrato (3.6/5) and Legato d'archet (3.6/5): the vibrato should be controlled and moderate to color long lines without obscuring articulation, and the bow legato demands smooth direction and bow placement changes to keep the melodic connections intact. As a Classical-period sonata, it belongs to Mozart's chamber-music output where the dialogue between violin and piano is central. I do not provide a reference recording because I am not 100% certain of a specific, widely recognized performance for this exact sonata.

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.
