An examination of the chance elements in Witold Lutosławski's music, with particular attention to its function as a model for compositional practice : a thesis and portfolio presented in fulfillment of the requirements for the degree of M.Mus. in Composition at the New Zealand School of Music, Wellington, New Zealand

Abstract

This thesis studies the use of aleatory techniques in Witold Lutoslawski’s music and the issues that arise when using aleatoricism, a branch of textural composition that has room for exploration. I focused my study on three of Lutoslawski’s major works, analysing his approach to aleatoricism, form, and macro- and micro-rhythm. I wrote three works for the portfolio component. My approach to aleatoricism differed in each work. Through studying Lutoslawski and my own composition, I came across practical issues in creating the score, issues with performers, and compositional problems. However, once these issues were worked though, aleatoricism is a exciting compositional device that is not yet tired.
