Scriabin's Prelude Op. 37 No. 1 is a profoundly melancholic and harmonically complex work from his later period. It is distinctive for its ethereal atmosphere and haunting melodic contours.
Achieving the subtle harmonic colors and the deeply expressive melodic line requires exceptional control of touch and pedaling.
4 Preludes (Op.37) is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 8.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 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.37) lasts about 4 minutes.
