This week's selection for The Gaggle Music Club is Alexander Scriabin’s Prometheus: The Poem of Fire, Op. 60. This piece of music is undoubtedly one of the composer's most ambitious and mystically charged works, embodying his late-period exploration of synesthesia, theosophy and musical-symbolic transcendence.

Scriabin was deeply influenced by theosophy, a spiritual movement that sought to unify Eastern and Western religious traditions. By the time he composed Prometheus in 1910, he had become convinced that music could serve as a vehicle for spiritual enlightenment—a way to elevate human consciousness and bring about mystical transformation.

In theosophy, Prometheus (the mythological figure who gave fire to humanity) symbolized divine wisdom, illumination and transcendence. Scriabin saw him as an archetype of artistic and spiritual liberation, mirroring his own aspirations for his music.

Scriabin had long envisioned creating an ultimate artistic experience—something all-encompassing that would combine music, color, movement, and ritual to trigger a cosmic awakening. Prometheus serves as a precursor to this larger vision, experimenting with the integration of light and sound.

Scriabin is said to have had a condition known as synesthesia—a condition whereby the brain associates one sensation with another. In his case, sounds would evoke colors. He developed a "color-music" system, in which each key became associated with a specific hue. In Prometheus, he introduced a part for "luce" (light keyboard)—an instrument meant to project colored light in accordance with the harmonies played. This system was meant to enhance the mystical effect of the music by uniting sound and visual sensation.

Prometheus is a symphonic poem with piano soloist, though it is neither a conventional concerto nor a traditional symphony. It follows a tripartite form resembling a tone poem.

The first performance of the work in Moscow in 1911, conducted by Serge Koussevitzky, bewildered audiences. Many listeners struggled with its harmonic language and lack of traditional structure. However, others recognized it as a visionary step forward in modern music.

Some critics dismissed it as "mystical gibberish" and "unintelligible chromatic madness." Others praised the work for its audacity. Rachmaninoff, though a traditionalist, admired the piece. Stravinsky, however, dismissed it as the product of mystical self-indulgence.

Subsequently, Prometheus gained recognition as a groundbreaking work in orchestration and coloristic harmony. Notable conductors such as Leonard Bernstein, Pierre Boulez and Vladimir Ashkenazy have championed the work.

Prometheus serves as a bridge in Scriabin's oeuvre between his earlier, Chopin-influenced period and his late-period transcendental vision that culminated in his unfinished magnum opus, Mysterium, a mystical work that the composer believed would trigger the apocalypse and human transformation.

Scriabin died in 1915, before realizing his full vision, but Prometheus remains his most complete synthesis of music, mysticism, and synesthetic ambition. The work has come to be regarded as one of the great experimental masterpieces of early 20th-century music.
