Arioso with 20 Variations in C major, H.259, Wq.118, no. 10
Classical Variations Piano solo ~13 min
In brief

The Arioso with twenty variations in C major has a singing yet often winding character: the simple theme unfolds and is reshaped through contrasting episodes that require a sustained lyrical thread. Concrete technical points to work on: Analyse harmonique (3.8/5) — you will need to quickly identify modulations and passing basses to balance inner voices and secure harmonic transitions between variations; Nuances (2.5/5) — the challenge here is to shape each variation with subtle dynamic shading, using controlled touch and phrasing rather than large dynamic leaps. The piece belongs to the composer's late classical keyboard output, where variations function as an expressive workshop balancing sensitivity and formal clarity.

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.
