B. London Music Book K. 15a-15qq
Piano solo ~30 min
In brief

This piano piece projects a bright, crisp character built on short motifs and clear rhythmic drive that call for forward motion rather than introspection. Technically, Sight-reading (2.5/5) will require you to process recurring figures and simple hand shifts quickly, and Touch control (2.5/5) asks for precise attacks and releases to preserve the clarity of accents and the transparency of inner voices. The work belongs to the body of keyboard pieces attributed to Mozart in youthful collections and occupies a place in his catalogue as a modest, elementary piece reflecting the period's didactic keyboard practices. I do not give a reference recording here because I am not certain of a widely recognized interpretation for 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.
