This blues piece by Gerber is a brief, lyrical work designed for intermediate students to explore non-traditional tonality. Its distinctiveness comes from the sparing use of dissonance against a stable, melodic bass line.
Ensure the melody is well-voiced above the accompaniment in a sustained, cantabile style.
Comparable difficulty and character — good candidates for what to learn next.
Blues is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 3.
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 Blues lasts about 2 minutes.
Blues is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
