Pro tanec, H.158
Modern Piano solo ~2 min
In brief

Pro tanec presents a dance-like, slightly piquant character, alternating lively ostinatos with brief coloristic respites that suggest both popular movement and a hint of irony. You will face specifically the Polyrhythmie 2 contre 3 (3.1/5), which requires true hand independence where one hand divides the beat into two against the other's three while keeping a steady pulse, and the Style impressionniste (3.1/5), here implying careful use of pedal and voice balance to bring out harmonic colors without blurring articulation. The piece belongs to Martinů's modern period and sits among his piano miniatures where he experiments with short, dance-based forms rather than large-scale syntheses. I do not give a recording recommendation because I am not fully certain of a single widely recognized 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.
