...sofferte onde serene...
Piano solo 14 min
In brief

The piece projects a chiaroscuro, meditative mood with slow breaths and floating resonances that prioritize sound-space over virtuosic display, asking for listening as much as doing. Technically you will face specific demands in Phrasing (2.5/5) and Legato (2.5/5): phrasing here means shaping long lines with subtle changes of emphasis and breathing points, while legato requires very controlled note connections through precise fingering and release to maintain continuous sound. The work belongs to an experimental strand of the solo piano repertoire and, given the unknown period, should be seen as an introspective contribution within the composer's catalogue rather than a youthful study or a major cycle. I do not give a reference interpretation because I am not fully certain of a definitive recording for this specific piece.

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.
