"The music of "hyperpianist" Denman Maroney (born 1949) is inspired by nature and the music of John Cage, Ornette Coleman, Henry Cowell, Duke Ellington, Charles Ives, Scott Joplin, Olivier Messiaen, Thelonious Monk, Conlon Nancarrow and Karheinz Stockhausen among others. Maroney plays what he calls hyperpiano, which involves bowing and sliding the strings with copper bars, steel cylinders, Tibetan prayer bowls, rubber blocks and CD cases and gives him a unique sonic vocabulary. He also uses a system of temporal harmony based on the undertone series that allows him to improvise and compose in several tempos at once.

Maroney also has worked with musicians Tim Berne, Jane Ira Bloom, Jon Deak, John King, Garrett List, Roger Miller, Michael Moore, Bob Ostertag, William Parker, Bobby Previte, Ed Schuller, Elliot Sharp and Peter Zummo among others, and dance and theater artists Davidson Lloyd, Sin Cha Hong, Tom Keegan, Tom Lillard, Erin Martin, Wendy Osserman and Mel Wong among others.

Maroney was educated at Cal. Inst. of the Arts (MFA '74), Bennington College and Williams College (BA '71). His teachers included John Bergamo, Alan Chaplin, Bill Dixon, Jimmy Garrison, Leonid Hambro, Ingram Marshall, Steven Mosko, Morton Subotnick, and James Tenney."
