These recordings are found automatically, and the machine still gets it wrong. One click from you — yes or no — fixes the catalogue for every musician who opens this page after you. Across our 10,000 works, your answer is our only real quality check.
An arrangement or transcription is fine: if you recognise the work, answer yes. Answer no if it is a different work, a different composer, or if the recording does not play.

Is this the right work?
No account is required and no personal data is collected.
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 prelude has a dark, tense character, more angular and driven by sharp accents than by a singing melody. You will notably face Passages rapides (2.5/5), which require quick, even finger shifts to keep motifs clear, and Contrôle du toucher (2.5/5), which calls for fine regulation of pressure and wrist release to balance voices and preserve the depth of the bass. The period of composition is listed as unknown and this piece is outside Chopin’s well-known cycle of preludes, so it sits somewhat on the margins of his catalogue. I am not giving a reference interpretation because I am not 100% certain of an authoritative recording for this specific piece.
