Estimated from our difficulty score, not taken from an exam syllabus. Checked against 333 works on the ABRSM syllabus: the exact grade is right 7 times out of 10, and within one grade 99 times out of 100.
Difficulty estimate by MusicCoach on a scale of 1 to 100.
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.
Each suggestion combines difficulty gap, risk, confidence and skill overlap. The first two cards in each column are the most useful pedagogically.

The Lento opening leading into an Allegro agitato produces a nervous, taut character, with percussive outbursts that interrupt a veiled melodic line and demand constant shifts between tension and release. Technically, expect to work on Octaves (2.5/5) — here you must control evenness, touch and wrist relaxation to maintain projection without tension — and General technique (2.5/5), meaning management of contrasting attacks and quick accompaniment figures while keeping inner voices clear. In the composer's catalogue the sonata stands among his piano sonatas and reflects a mature stage of his pianistic writing. I do not have a recording or performer reference I can cite with certainty for this specific work.
