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.

The piece presents a taut, relentless character: the subject enters with a crisp attack and the close imitations produce a continually shifting contrapuntal texture with few natural breaths. Technically you should focus first on Polyphony for three or more voices (4.4/5) — that requires keeping independent lines clear by using secure fingerings and differentiated articulation for each voice — and on Harmonic analysis (4.4/5), so you can anticipate progressions and adjust dynamics and thumb placement in the bass during modulations. From a contextual standpoint it belongs to the Baroque period and is listed in the BWV Anhang, placing it among Bach-related contrapuntal pieces for which attribution has been questioned.
