This set is divided in three preludes :

No.1 : Db Major
No.2 : Bb Major
No.3 : C major

Three pieces full of mobility, with ambiguous yet relatively consonant harmonies. The first, delicate and vaporous, features lightly ascending lines—typically Scriabinesque—like fleeting breaths. The second, meditative, evokes Gothic and night-like sonorities, caught between resignation and flashes of grandeur. The last, ferocious, feels like a modernized Schumann.
