A largely obscure salon piece, this work by Mary Bowden represents the amateur domestic repertoire of the late 19th century. It is musically simple but effective in its use of traditional harmonic patterns.
The challenge lies in keeping a steady rhythmic 'sway' that does not become mechanical.
Comparable difficulty and character — good candidates for what to learn next.
Barcarolle (Op.15) is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 5.
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 Barcarolle (Op.15) lasts about 2 minutes.
