Scriabin's Prelude Op. 22 No. 1 is a majestic and powerful piece, known for its rich harmonies and emphatic statements. It is distinctive for its dramatic opening chords and subsequent lyrical unfolding.
Developing the strength and control for the large chords while maintaining tonal quality is the main technical challenge.
4 Preludes (Op.22) is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 6.
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.
A typical performance of 4 Preludes (Op.22) lasts about 3 minutes.
