Alexander Scriabin's Fantasie in B minor, Op. 28, was written in 1900. This is a single sonata form movement which bridges the gap between Scriabin's third and his fourth sonata. Scriabin wrote this piece during an otherwise compositionally unproductive period during his tenure at the Moscow Conservatory. The first edition was published by Belaieff.
The piece's existence may have been forgotten by the composer. According to Leonid Sabaneyev, when Sabaneev started to play one of its themes on the piano in Scriabin's Moscow flat (now a museum), Scriabin called out from the next room "Who wrote that? It sounds familiar". "Your 'Fantaisie'", was the reply. Scriabin said, "What 'Fantaisie'?". This story, told by Sabaneev and repeated by Faubion Bowers in his biography of Scriabin, may however be apocryphal. At any rate, as Sabaneev saw fit to fake Scriabin's death-date and otherwise make free with facts, his recountings of otherwise uncorroborated stories are best taken with a grain of salt. Be that as it may, Faubion Bowers' extensive documentation of Scriabin's concert programs shows no evidence of Scriabin having played the piece in public.
The Fantasy begins with ambiguous, open harmony not unlike that which Scriabin used for the opening of his second sonata, known as the Sonata-Fantasy. The opening is clearly in B minor, but the tonic is consistently avoided: a technique used extensively in Chopin's ballades, in Wagner's Tristan und Isolde, and by Scriabin himself in his third and fourth sonatas. The opening is characterized by an inexorably descending bassline and a melody that alternately struggles upwards and plunges dramatically back down in jagged gestures.
This brooding opening gives way to one of Scriabin's most beautiful melodies, a second subject in D major. The melody is treated canonically, with multiple voices echoing above an extremely widespread left-hand accompaniment. The closing groups, also in D major, are grand and confident with rhythmic obsessiveness and directional gestures characteristic of Scriabin's heroic writing.
In the recapitulation, the first subject is extensively elaborated with sweeping arpeggios in both hands. It is, however, truncated, giving way quite rapidly to a transition to the second theme. The second subject, meanwhile, is recapitulated in grandeur rather than tenderness: an apotheosis not unlike the thematic transformation of the main subject in Chopin's first Ballade from its initial tender statement in Eb major to its grand exuberance in A major.
