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 E minor prelude has a meditative, slightly restless character, built on a continual pattern of arpeggios that calls for an inward, singing approach rather than virtuosic display. Technically, you will need to focus on Legato (3.3/5) to connect the arpeggiated voices with flexible fingerings and controlled wrist motion to preserve a melodic line, and on Baroque Ornaments (3.1/5) which require short, precise executions (mordents, appoggiaturas) placed rhythmically and absorbed into the musical flow without weighing it down. As a Baroque piece, this prelude belongs to Bach's instructional and early keyboard material that explores simplified counterpoint and keyboard diction, and it sits among works that informed his later keyboard compositions. I do not give a reference recording here, since I am not fully certain of a single definitive interpretation for this specific version.
