abstract: ABSTRACT Torse III (1965) by Akira Miyoshi, Two Movements for Marimba (1965) by Toshimistu Tanaka, and Time for Marimba (1968) by Minoru Miki have remained “tour de force” pieces in the marimba repertoire since their inception nearly fifty years ago, yet they continue to present significant performance and interpretative issues to each new generation of marimbists. This document will serve as both a performance guide for advanced marimba performers, as well as provide insight into the aesthetic qualities that contribute to their lasting artistic significance. Each piece will receive a designated chapter discussing the historical context, technical challenges, and general performance practices. The author will also present a designated chapter discussing the three over-arching aesthetic characteristics found in all three pieces: the use of the entire range of the instrument, the use of extreme contrasting dynamics and timbre, and the use of a common harmonic language. Torse III, Two Movements, and Time were famously performed by Keiko Abe on her first classical marimba recital in 1968. This document will also help bring to light the enormous impact this recital had on the history of the marimba, as marimbists throughout the world today are forever indebted to Abe’s efforts. / Dissertation/Thesis / Doctoral Dissertation Music 2016
