John Cage, (1912-1992) pioneer in new music, innovator, inventor of the happening and philosopher, writer and artist was one of the most creative forces of the twentieth century. His earliest works were 25-tone contrapuntal compositions. He later developed a strong interest in writing for percussion ensembles and collected instruments that were both found and made. He conducted his own percussion orchestras and discovered that they were the answer to his philosophy of the sounds of the future. He considered percussion music the transition from keyboard-influenced music to music which allowed for all sounds and silences. From 1939-1951 John Cage composed several works for prepared piano that used time as a structural device. Many of these works were written for the dance in collaboration with Merce Cunningham. This document addresses the historical significance of these works and relates Time to other areas that influenced Cage--including Zen and the Dance. This document provides descriptive analyses of Bacchanale, Music for Marcel Duchamp and selected Sonatas from the Sonatas and Interludes. To this writer's knowledge there have not yet been any analyses of Bacchanale or Music for Marcel Duchamp. The analyses reveal Cage's primary structural techniques in which he uses duration of spaces of time. Time lengths and the square root method appear to be the most important. These techniques first appeared in Imaginary Landscape #1 and First Construction in Metal--both dating from 1939. A brief description of all his prepared piano works is included to demonstrate Cage's commitment to rhythmic structuring. All of these works have been studied by this writer and several have been performed in concert by this writer. These include: Music for Marcel Duchamp, Primitive, For a Valentine Out of Season, A Room, Prelude for Meditation, Amores (Movements I and IV), and selected Sonatas from Sonatas and Interludes. A section has been included which explains the nature of materials used for preparations and their timbral effects. A Conclusion is provided demonstrating that Cage chose rhythm over harmony to structure his music. This information is drawn from the influences on Cage, his early percussion works, procedures employed in the percussion works and transferred to the prepared piano and the influence of dancers and Oriental philosophy. An Appendix is included with charts of the Sonatas. A Bibliography which shows the references consulted is included.

When John Cage invented the prepared piano in 1940, he created a sound world and body of music unlike anything heard before. The innovative music he wrote for prepared piano requires a completely new approach to performance, and expands our understanding of the piano's capabilities. This study will examine the main prepared piano works by John Cage, with a detailed analysis of the Sonatas and Interludes. Cage's Table of Preparations will be examined to establish an aesthetic rationale for this preparation. Different modes of listening will be explored through a selection of the Sonatas and Interludes recorded in three different technological systems - conventional AB 2.0, surround 5.1, and Disk Jecklin. The latter allows for a true "surround sound" experience as Cage himself might have heard his own pieces. Included is a compact disc of selections from Sonatas and Interludes recorded in each of the three technological systems. / by Inara Ferreira. / Thesis (M.A.)--Florida Atlantic University, 2010. / Includes bibliography. / Electronic reproduction.
