Nun komm der Heiden Heiland, BWV.659-661
Baroque Piano solo ~10 min
In brief

This piece has a measured, singing solemnity, with the cantus firmus clearly projected above sometimes polyphonic accompaniment; the mood asks for rhythmic clarity and relaxed articulation so the vocal line can breathe. You will notably face the skill Lecture clé de fa (3.1/5): you must read and place the bass voices confidently to balance both hands, and Ornements baroque (3.1/5), which requires executing short ornaments (brief trills, appoggiaturas) cleanly and discreetly on an instrument not originally intended for those effects. The work belongs to Bach’s Baroque chorale settings, where chorale form is used to explore counterpoint and harmonic relief. I do not give a reference interpretation because I prefer not to cite a specific recording unless I am certain of its direct association with this exact 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.
