This signed sheet music is for Music in Fifths by Philip Glass, autographed by the composer himself. Composed in 1969, Music in Fifths is one of Glass’s most radical and uncompromising early minimalist works. Written shortly after his return from studying with Ravi Shankar in India, the piece applies a strict process in which every melodic line moves exclusively in parallel fifths. This unusual constraint creates a stark, almost mechanical sound world that was deliberately provocative—challenging traditional Western notions of harmony and counterpoint. Its driving pulse, relentless repetition, and gradual transformations exemplify Glass’s minimalist language while also highlighting his willingness to experiment with bold and unconventional compositional methods. Philip Glass (born 1937) is celebrated as one of the most influential composers of the 20th and 21st centuries, pioneering the minimalist movement while reshaping the landscape of contemporary classical music. His works, from the operas Einstein on the Beach and Akhnaten to orchestral works and acclaimed film scores, are known for their hypnotic structures, rhythmic vitality, and emotional resonance. Music in Fifths, though austere, was a crucial step in his evolution, reflecting his early exploration of strict process-based composition and foreshadowing the broader stylistic innovations that would define his career. Owning this signed sheet music for Music in Fifths is more than a collectible—it’s a rare piece of avant-garde music history tied to Philip Glass’s early experiments that shaped modern minimalism.
