Henry Cowell (1897-1965)
Born and raised in Northern California. Irish heritage has an important influence—both musical and extra-musical—on his composition. Self-taught musician who composed and performed his first solo piano works as a teenager Proposed a number of rhythmic, timbral, and harmonic innovations including inside piano techniques and tone clusters. A key figure among a group of “ultra-modernist” American (and international) composers in the 1920s and 1930s. Influential to many composers, including Béla Bartók, Conlon Nancarrow, and John Cage. Organized New Music Society (1925); co-founded Pan-American Association of Composers (1928); published New Musical Resources (1930). His music turned strikingly conservative beginning in the 1940s.

Elliott Carter (b. 1908)
Born in New York City; as a teenager was encouraged to pursue music by Charles Ives. Studied English literature and music at Harvard University; further composition studies with Nadia Boulanger (1932-35). Early works influenced by the neoclassicism of Stravinsky and Hindemith. Abandoned diatonicism and populist musical aesthetic in the late 1940s, adopting an atonal and more rhythmically sophisticated language. Pioneered a technique known as “metric modulation” in the early 1950s.
Background
Music is characterized by complex and contrapuntally rich textures comprised of multiple polyrhythmic strands. Organic use of pitch material, based on pitch-class sets and interval classes. Instruments often treated as “characters” within a dramatic construct. Two-time recipient of the Pulitzer Prize in Music (1960, 1973)

Conlon Nancarrow (1912-1997)
![Page 26: Explorations in Time: Rhythm, Meter, and Tempo](https://reader034.fdocuments.in/reader034/viewer/2022052308/5858c0021a28ab6e328e3354/html5/thumbnails/26.jpg)
Conlon Nancarrow (1912-1997)
Born in Texarkana, Arkansas. Played jazz trumpet in his youth; later studied composition in Cincinnati and Boston with Walter Piston, Roger Sessions, and Nicolas Slonimsky. Joined Communist Party; fought with the Abraham Lincoln Brigade against Francisco Franco in the Spanish Civil War (1937-39). Moved to Mexico City in 1940 to avoid persecution for his Communist affiliation; lived there for the remainder of his life. Technical demands of early works yielded unsatisfactory results in performance, forcing him to seek alternative solutions. Adopted player piano after reading Cowellʼs New Musical Resources. Composed in relative obscurity until being “discovered” in the late 1970s, prompting international dissemination of his work.

Conlon Nancarrow (1912-1997)
Harmonic and rhythmic language reflects a distinct jazz influence (particularly in his early works), reminiscent of Art Tatum. Explored complex temporal relationships through canonic studies; “temporal dissonance.” His works successfully combine mathematical elegance with musical expressiveness and unabashed humor. Examples of unusual proportional relationships in Nancarrowʼs Studies:

Conlon Nancarrow: Player Piano Study No. 21 — “Canon X” (1948-60)Analysis
Rate of tempo change is a function of the tempo. Each voice is based on a melodic cycle of 54 notes:
Initial tone of melodic cycle is omitted with each pass (e.g., 54, 53, 52,…3, 2, 1). Series is transposed with each pass according to a separate four-and-a-half twelve-tone sets (=54 notes). Harmonic language evolving toward “pantonality.” Last study to utilize incremental hole-punching mechanism.
