Lumbye was the 'Strauss of the North,' and his Camilla Polka is a bright, rhythmic crowd-pleaser. It follows the traditional structure of 19th-century dance music.
Ensure the repeated notes are crisp and energetic throughout the performance.
Camilla Polka is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 5.
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 Camilla Polka lasts about 3 minutes.
