Piano Sonata b minor op. 5
Sonata Piano solo
In brief

This B minor Sonata has a tense, dramatically contrasting character, switching between virtuosic outbursts and more contrapuntal episodes where rhythmic urgency prevails. Technically you will face, in particular, Phrasing (2.5/5) — you must shape long lines across breaks and detachments, anticipating voices to form coherent phrases — and Polyphony of three or more voices (2.5/5), which requires isolating and balancing inner voices through finger independence and subtle changes of support. It is an early work in Busoni's catalogue (Op. 5) that already reveals his taste for contrapuntal density within the sonata form.

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.
