Violin Sonata no. 4 in C major, op. 72: III. Largo con gran espressione
Romantic Sonata Violin and Piano
In brief

This Largo con gran espressione creates a tense, contemplative atmosphere of long singing lines and dramatic pauses where every note feels deliberate. Technically, expect to work on Vibrato (3.6/5) to keep a warm, steady tone on sustained notes and on Legato d'archet (3.6/5): here the gesture requires smooth bow changes with controlled weight and speed to connect phrases without bumps. As a Romantic chamber piece, the Sonata op. 72 belongs to Reger's dense, harmonically rich output for violin and piano, where contrapuntal writing and expressive depth are central. I do not give a recommended recording here because I am not sufficiently certain of a single definitive reference.

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.
