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.

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 A minor fugue unfolds with concentrated drive and sustained tension: subjects overlap and answer each other often in a moto perpetuo fashion, creating a sense of forward propulsion rather than relaxed lyricism. You will face mainly the skill “Polyphony for three voices or more (4.4/5),” here requiring you to project independent lines and balance soprano, alto and bass simultaneously with precise fingers and controlled releases, and “Harmonic analysis (4.4/5),” which means identifying modulation points and cadences to shape accents and resolutions so the contrapuntal design is clear. A work of the Baroque, it sits in Bach’s output as an example of his counterpoint for solo keyboard, emphasizing voice clarity over flashy ornamentation. I do not list a reference interpretation because I prefer not to risk naming an incorrect recording.
