Aux Hirondelles is a charming modern character piece by Colette Mourey that captures the flight of swallows. It is musically notable for its light, nimble texture and whimsical use of dissonance.
The technical focus is on producing a light, 'flitting' touch to capture the avian theme effectively.
Comparable difficulty and character — good candidates for what to learn next.
Aux Hirondelles 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 Aux Hirondelles lasts about 2 minutes.
