Melnyk was born in Munich, Germany to Ukrainian parents in 1948. His family moved to Winnipeg, Canada in the early '50s in order to flee the Communist expansion. After graduating from St. Paul's College in Winnipeg with a degree in Latin and philosophy, and earning an M.A. in philosophy at Queen's University in Kingston, Ontario, Melnyk moved to Paris and played piano for modern dance classes. He developed his technique while in Paris, inspired by the minimalism movement and frustrated with what he viewed as a lack of innovation in the previous three centuries of piano playing. He moved back to Canada in 1975 and began composing works, as well as presenting lectures on continuous music throughout Canada and Europe. His debut album, KMH, was issued by Toronto-based Music Gallery Editions in 1979, followed by the double LP The Lund-St. Petri Symphony (Apparition Records) in 1981. Also that year, he published Open Time: The Art of Continuous Music, a book explaining his method. Numerous LPs of his music were released through Bandura Records, or self-released as cassettes.
Despite his prolific release schedule and his record-setting abilities, Melnyk's work largely went unnoticed until the 21st century. Avant-garde classical label Unseen Worlds reissued Melnyk's debut album in 2007 (minus the first ten minutes of the original recording, as the beginning of the master tapes had been damaged), and the release received critical acclaim. This led to additional releases on labels including Hinterzimmer (Windmills) and Erased Tapes (Corollaries, Evertina, Rivers and Streams), as well as a collaboration with guitarist James Blackshaw titled The Watchers (Important Records). In 2016, Melnyk made his major-label debut with Illirion, released by Sony Classical. He returned to Erased Tapes with 2018's Fallen Trees. ~ Paul Simpson, Rovi
