This is a piano transcription of a Schubert Lied, often attributed to various arrangers including Napoléon Coste. It is valued for its vocal melodic quality and the characteristic rocking motion of the barcarolle form.
Control the touch to ensure the melodic line sounds vocal, rather than percussive.
Barcarolle (by Schubert) 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.
