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.
