Piano Sonata no. 4 in C major, op. 38
Romantic Sonata Piano solo ~17 min
In brief

This sonata projects a bright, sunny character with lyrical episodes alternating with virtuosic flashes: you must keep rapid passages clear while shaping singing, flexible phrases. You will be especially challenged by Connaissance des formes (3.6/5) — you need to internalize and shape the large sections, manage repeats and transitions so the overall form remains audible — and by Analyse harmonique (3.6/5), which requires anticipating modulations and adjusting voice-leading and pedaling to support harmonic shifts. From a contextual point of view it belongs to the Romantic period and sits in Hummel's output as a work that bridges classical transparency and early romantic color.

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.
