Set of preludes organized in six pieces :

No.1 : Maestoso (C major)
No.2 : Allegro (A minor)
No.3 : Andante (G major)
No.4 : Allegro (E minor)
No.5 : Allegro (D major)
No.6 : Presto (B minor)

By looking at the tonalities, it is clear that Scriabin originally intended to create another set of 24 preludes with these compositions (after completing his cycle of preludes op.11). This plan, however, was never completed, as the subsequent opus do not consistently follow the same tonal organization, and the total number of preludes only reaches twenty-three. Op.13, as well as Op.15 still remain stylistically close to Chopin, while Op.16 opens new harmonic horizons, with colors reminiscent of Debussy and Satie.

No.1 is a noble march with vaporous colours and great serenity. Scriabin would generally maintain this tradition of opening his prelude sets with a noble, luminous, soft and resonant piece.

No.2 is a fast-paced étude, filled with chromaticism and fast lines that are reminiscent of certain Chopin études (No.2 Op.10).
