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.

Official level, taken from the exam syllabus.
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 Sinfonia in B-flat has a lively yet focused character, alternating brisk motifs with consonant passages that require crisp articulation to bring out the individual lines. The main technical challenges for the student are clearly Indépendance des mains (4.6/5) and Polyphonie à trois voix ou plus (4.6/5): the right and left hands must maintain distinct rhythmic and dynamic lines while simultaneously managing three independent voices, which requires precise finger control for detachment and careful balancing so each voice sings. The piece belongs to Bach's pedagogical, polyphonic keyboard repertoire designed to develop contrapuntal control. I do not provide a reference performance here because I cannot reliably confirm a single definitive recording for this specific Sinfonia.
