Paul Wachs was a popular French composer of salon piano music known for his light and idiomatic writing. This bolero demonstrates the typical ornamental flourishes and rhythmic flair found in high-society parlor music.
Developing a fluid and graceful approach to the melodic ornaments is essential for this piece.
Comparable difficulty and character — good candidates for what to learn next.
Boléro is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 5.
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 Boléro lasts about 5 minutes.
Boléro is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
