An Examination of the Chance Elements in Witold Lutosławski's Music, with Particular Attention to Its Function as a Model for Compositional Practice
This thesis studies the use of aleatory techniques in Witold Lutosławski'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 Lutosławski'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 Lutosławski 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.
