This Barcarole by the Finnish composer Erkki Melartin captures the typical swaying rhythmic motion of Venetian boat songs within a Nordic Romantic harmonic language. It is distinguished by its expressive, song-like melodies and lush, mid-range textures.
The primary challenge is maintaining a consistent, liquid rhythmic pulse while shaping the lyrical phrases with subtle rubato.
Comparable difficulty and character — good candidates for what to learn next.
Barcarole (Op.59 No.1) is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
