Astir is a charming late-Romantic salon piece by French-American composer Irénée Bergé. It is characterized by its lighthearted melodic contour and elegant phrasing typical of early 20th-century drawing-room music.
Focus on maintaining a light, graceful articulation throughout the melodic lines.
Comparable difficulty and character — good candidates for what to learn next.
Astir 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 Astir lasts about 3 minutes.
Astir is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
