Black and Blue is a melancholic salon piece reminiscent of early jazz-inflected popular music. It features lyrical, bluesy melodic lines floating over a broken-chord accompaniment.
Use flexible, expressive rubato to capture the sentimental character of the melody.
Comparable difficulty and character — good candidates for what to learn next.
Black and Blue is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 4.
You should be comfortable at Henle level 3 — meaning you can already play level 2–3 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Black and Blue lasts about 4 minutes.
