Young considers "The Well-Tuned Piano"—a permuting composition of themes and improvisations for just-intuned solo piano—to be his masterpiece. Young gave the world premiere of "The Well-Tuned Piano" in Rome in 1974, ten years after the creation of the piece. Previously, Young had presented it as a recorded work. In 1975, Young premiered it in New York with eleven live performances during the months of April and May. As of October 25, 1981, the date of the Gramavision recording of "The Well-Tuned Piano", Young had performed the piece 55 times. In 1987, Young performed the piece again as part of a larger concert series that included many more of his works. This performance, on May 10, 1987, was videotaped and released on DVD in 2000 on Young's label, "Just Dreams". Performances have exceeded six hours in length, and so far have only been documented several times. It is strongly influenced by mathematical composition as well as Hindustani classical music practice.
