Scriabin had at least three major periods: Early, Middle, and Late.Here's a more detailed, although rough and imperfect, breakdown:Juvenilia (Romantic). Includes the G# and Eb minor sonatas, and many short pieces.Early Romantic. Op. 6 to Op. 14. (Op. 2 No. 1 fits here, too.)Mid Romantic. Op. 15 to Op. 21.Late Romantic. Op. 22 to Op. 28.Impressionism/sensuality. Op. 30 to Op. 33 No. 2.Impetuosity, introspection, increasing abstraction. Op. 33 Nos. 3 and 4 to Op. 45.Ecstasy (energetic abstraction). Op. 48 to Op. 56.Introspection, sensuality. Op. 57 to 58.Impure spirits. Op. 59 to 63.Purifying light. Op. 64 to Op. 65.Labyrinth. Op. 66.Evil. Op. 67 to Op. 69.Infinity. Op. 70 to Op. 71.Apocalypse. Op. 72 to Op. 73.Post apocalypse. Op. 74.(Op. 60 is difficult to classify. It falls well within the late period, however.)
Is this your personal interpretation of how the pieces are classified?
I wish you could download the Poemes here as well as the Etudes and Preludes. My favorite pieces of Scriabin are Opus 59 no. 2 (prelude) and Opus 69 no 2 (Poeme). Vers La Flamme is fantastic. Scriabin was a wonderful composer. For me, he is on a par with what Mahler did for the orchestra, though of course Scriabin's pieces are miniature in comparison. A much more interesting composer than Rachmaninoff. Some pianist I met called Rachmaninnoff's music a cheap thrill. I would not go that far, but I think Scriabin certainly goes deeper.
