Violin Sonata no. 1 in C sharp minor, op. 21, BB84, Sz.75
Modern Sonata Violin and Piano
In brief

The piece unfolds in a tense, raw atmosphere where short, percussive figures alternate with abrupt breaths, giving the music a nervous, almost primitive drive rather than a smooth cantabile line. Technically you will need to focus on phrasing (3.6/5) — here that means shaping very short, jagged gestures by precise bow distribution and managing breaks in the line — and on harmonic analysis (3.6/5), since spotting the chromatic progressions and their moments of rest is essential to highlighting tension and release. This sonata belongs to Bartók's modernist period and forms part of his chamber-music output for violin and piano, where he explores denser harmonic and rhythmic language than in his earlier works.

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.
