In this work, a new framework is developed for the unrestricted manipulation of timbre in musical composition. Unlike other perceptual musical attributes such as pitch or loudness, timbre is not a one-dimensional property, and is not easily manipulated in a flexible yet precisely-controlled manner. The multi-dimensional nature of timbre has been previously studied using multi-dimensional scaling (MDS) techniques. The outcome of a study involving timbre and MDS is typically referred to as a timbre space. Previous timbre spaces have been suitable for a high-level description of some of the underlying dimensions of timbre, but not to a satisfying degree, and have not been suitable for subsequent synthesis of timbre. In this work, four design goals are proposed for a timbre space suitable for composition, along with ways in which to satisfy them. They are: perception, synthesis, interface, and modularity. The primary focus of this work is on the first goal of perception. Understanding the mental representation of timbre at a fundamental level is vital to achieving an effective and compact system for timbre manipulation. Due to the current lack of a satisfying model of timbre perception, we devise new methods and propose new ideas to develop one. As a result, contributions of this work include an improved experimental procedure for the study of perceptual spaces, theoretical contributions to the study of timbre, a novel timbre space suitable for synthesis, a new periodic waveform analysis technique, and a detailed blueprint for the implementation of a system for timbre manipulation in composition.
