This piece by Romanian composer Serban Nichifor is a character piece that draws on Americana themes. It is musically distinctive for its neo-tonal language blended with 20th-century harmonic sensibilities.
The primary challenge is maintaining a consistent lyrical line against varied rhythmic accompaniment.
Comparable difficulty and character — good candidates for what to learn next.
American Air is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 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 American Air lasts about 3 minutes.
