Violin Sonata no. 7 in C major, op. 139
Romantic Sonata Violin and Piano
In brief

Reger's Violin Sonata in C major has an atmosphere that alternates between energetic, contrapuntal passages and lyrical romantic episodes, requiring both drive and sustained melodic line. The most demanding technical issues for the player here include Legato d'archet (3.6/5), which requires very controlled bow direction and speed changes to maintain a singing line, and Vibrato (3.6/5), which must be varied to support phrases without weighing down the texture. Placed in the Romantic period, the sonata belongs to Reger's chamber output that blends contrapuntal writing with a late-romantic harmonic language.

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.
