The Poem of Ecstasy
Alexander Scriabin's The Poem of Ecstasy (Le Poème de l'extase), Op. 54, is a symphonic poem written between 1905 and 1908, when Scriabin was actively involved with the Theosophical Society. It lasts about 20 minutes.
Scriabin sometimes referred to The Poem of Ecstasy as his "fourth symphony", although it was never officially called such and avoids the traditional division into separate movements. Although played as a single movement, there are traces of the classical sonata key-scheme that Scriabin had employed previously, but it is no longer structurally important. As described by Bernard Jacobson, "The form depends instead on the constant interpenetration and cross-fertilization of a multiplicity of tiny thematic units, most of them so sinuously chromatic as to subvert tonal feeling almost entirely beneath the vertiginous onslaught of shifting harmonic colors."
Much of the work has a feeling of timelessness and suspense, because of its rhythmic ambiguity and whole-tone-based dominant harmonies derived from Scriabin's "mystic chord" (since the whole tone scale has no leading tones, any harmony based on it will not lean toward any key in particular, allowing Scriabin to write pages of music with little to no tonal resolution).
The work can be split into three major theme groups: one group that is characterized by slower chromatic winding, one faster and more agitated group characterized by quick leaps and trills, and one featuring three themes presented by the brass (a horn fanfare to provide a rhythmic motif, a trumpet fanfare emerging from the surrounding texture, and a more lyrical trumpet theme). These three groups are presented separately at the outset of the piece, but are later developed and combined in different ways. The piece also builds to two major climaxes: one in the middle and one at the end. Both are built on themes from the third group and accompanied by string and woodwind tremolos and trills. At the second climax, Scriabin introduces low bells and organ, and maintains a trumpet and percussion ostinato throughout.
Scriabin wrote a poem over three hundred lines long to accompany the music, though not to be recited with it. The poem tracks the ascent of a spirit into consciousness, catalyzed by the recurring appearance of "trembling presentiments of dark rhythms" that later transform into "bright presentiments of shining rhythms" as the spirit realizes the excitement of the struggle against them, contrasted with the "boredom, melancholy, and emptiness" felt after victory over them. The ascent into consciousness is illustrated by the gradual shift from third-person "Spirit" to first person "I". Scriabin also based his fifth piano sonata on the poem, and in the first publication of the sonata he included the following lines:
He approved the following text for the program notes at the premier of the symphony:
The Poem of Ecstasy is the Joy of Liberated Action. The Cosmos, i.e., Spirit, is Eternal Creation without External Motivation, a Divine Play of Worlds. The Creative Spirit, i.e., the Universe at Play, is not conscious of the Absoluteness of its creativeness, having subordinated itself to a Finality and made creativity a means toward an end. The stronger the pulse beat of life and the more rapid the precipitation of rhythms, the more clearly the awareness comes to the Spirit that it is consubstantial with creativity itself. When the Spirit has attained the supreme culmination of its activity and has been torn away from the embraces of teleology and relativity, when it has exhausted completely its substance and its liberated active energy, the Time of Ecstasy shall arrive.
Modest Altschuler, who helped Scriabin revise the score in Switzerland in 1907, and who conducted the premiere with the Russian Symphony Society of New York on 10 December 1908,   reported that Scriabin's implied program (which does not appear in the score) is based on three main ideas: his soul in the orgy of love, the realization of a fantastical dream, and the glory of his own art. 
The work is scored for 3 flutes, piccolo, 3 oboes, English horn, 3 clarinets, bass clarinet, 3 bassoons, contrabassoon, 8 horns, 5 trumpets, 3 trombones, tuba, timpani, bass drum, cymbals, triangle, small and large bells, tam-tam, celesta, organ (harmonium if the organ is not available), 2 harps and strings.
That Poème de l'extase? Put it on loud. His music sounds like I think - sometimes. Has that far-off cosmic itch. Divinely fouled up. All fire and air. The first time I heard it I played it over and over. (...) It was like a bath of ice, cocaine and rainbows. For weeks I went about in a trance. Something had happened to me. (...) Every time a thought seized me a little door would open inside my chest, and there, in this comfy little nest sat a bird, the sweetest, gentlest bird imaginable. 'Think it out!' he would chirp. 'Think it out to the end!' And I would, by God. Never any effort involved. Like an étude gliding off a glacier.
In the movie Barfly, Poem of Ecstasy can be heard in one scene.
