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.

This F-sharp minor Sonata has a tense, nocturnal character, shifting between rugged, percussive episodes and more veiled, coloristic passages where timbre outweighs singable melody. Technically you will need to focus on Harmonic analysis (3.6/5) to anticipate the chromatic shifts and shape phrases without losing forward motion, and on the 2-against-3 polyrhythms (3.1/5) which here require independent hand control and precisely offset attacks to preserve polyphonic clarity. The piece belongs to the composer's modernist period and is part of his important contributions to the solo piano repertoire, blending orchestral textures with a late-romantic sensibility. I do not give a recommended recording because I cannot state with complete confidence a single definitive interpretation for this specific sonata.
