No.146 — Ostinato
Piano solo ~2 min
In brief

This piece has a mechanical, driven tension: the ostinato sets a motoric, almost percussive pulse that leaves little lyrical space, with distributed accents that shape the line rather than long melodies. Technical points: Staccato (4.6/5) here requires a very controlled detached touch in the repeated figures, so quick finger and wrist releases are needed to keep articulation crisp without weighing down the pulse; Rythmes pointés (4.6/5) demand fine rhythmic precision and consistent internal subdivision so the dotted accents remain steady within the ostinato. It belongs to Bartók’s piano output and reflects his interest in percussive writing and rhythmic experimentation within his keyboard repertoire.

Where this work sits
050100

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.
