Jesus schläft, was soll ich hoffen? BWV 81
Piano solo beta difficulty
In brief

The piece feels like a worried lullaby rather than a grand statement: a gently rocking pulse, suspended melodic lines and a fragile character that needs contained breathing. You will specifically face Phrasing (2.5/5), which here means shaping long, vocal-like lines on the piano by sustaining with controlled finger legato and subtle changes of hand weight, and Baroque Ornaments (2.5/5), which require crisp, short executions of mordents/trills governed by small wrist and finger articulations. The movement comes from Bach's cantata BWV 81 and belongs to his sacred vocal output of the Baroque period. I do not provide a reference performance to avoid risking an incorrect attribution.

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.
