Scriabin's early Op. 5 is a quintessential example of his Romantic period, characterized by its lush harmonies and expressive melodic lines. These nocturnes explore a tender and introspective musical language, typical of the genre.
The challenge lies in achieving a seamless blend of the melodic line and the rich harmonic accompaniment, with careful attention to rubato.
2 Nocturnes (Op.5) is rated Henle level 6 of 9 — advanced repertoire, roughly ABRSM grades 7–8. In the RCM system it corresponds to about level 9.
You should be comfortable at Henle level 6 — meaning you can already play level 5–6 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 2 Nocturnes (Op.5) lasts about 6 minutes.
