Allegro in G minor, K.312
Classical Piano solo 5 min
In brief

This Allegro in G minor opens with a biting energy and sustained dramatic tension where abrupt accents and rhythmic leaps produce a stormy, restless character rather than a lyrical one. You will need to focus on Style classique (3.1/5) — here that means clear attacks, clean phrase transitions and precise balance between right and left hands — and on Nuances (2.5/5), which require quick, controlled dynamic shifts and a sensitive handling of crescendi/decrescendi over short harmonic groups. Placed within Mozart's catalogue, the piece exemplifies his use of minor-key contrasts in keyboard writing and occupies a role as a dramatic keyboard movement. I do not give a specific recording recommendation because I am not certain of a single authoritative reference 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.
