Alexander Scriabin's 24 Preludes Op. 11 are early works that showcase his burgeoning Romantic style, influenced by Chopin but developing his own harmonic language. They are characterized by their intense emotional range and virtuosic demands.
Mastering the rapid figurations and achieving a rich, resonant tone are key challenges.
24 Preludes 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 24 Preludes lasts about 40 minutes.
