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 projects a raw, fragmented atmosphere, built from short gestures and sound effects that seem to gust and scrape through the sonic space rather than unfold a long melody. Technically, expect to focus on Technique générale (2.5/5), meaning precise attacks and physical control of rapid register shifts, and on Phrasing (2.5/5), here requiring micro‑phrases with internal breaths and abrupt endings; concretely this implies crisp detaché strokes on the cello and sharply cut chords or interruptions from the piano. The work belongs to Xenakis's output as an exploration of timbre and structural sound processes rather than conventional lyricism, consistent with his interest in textures and sonic architecture. I do not suggest a specific reference performance because I am not 100% certain of a definitive recording for this particular piece.
