A typical salon waltz from the late Romantic era by Édouard Garnier. It highlights the aesthetic of light, parlor-style piano music common in the late 1800s.
Focus on the left-hand placement to ensure the waltz bass does not overpower the delicate right-hand melody.
Comparable difficulty and character — good candidates for what to learn next.
Bonjour Suzon 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 Bonjour Suzon lasts about 3 minutes.
