This folio and accompanying commentary draw together my compositional work over the period of the PhD and plot the development and exploration of a number techniques which are to be found in varying degrees in each of the works but with different emphases. These techniques include the use of: parallel structures and metres to provide a sense of independence of compositional ideas; parallel tonal centres within overarching schema to control and draw thematic material together; the use of rhetorical musical gestures that seek to break free of their context; fragmentation and the accumulation of material in terms of quantity and density in order to facilitate a sense of change; the limitation of pitch material in order to create a sense of stasis; and the use of slow sustained melodies that lack a clear pulse in order to create a sense of musical events that are not bound by time.

This study is an exploration of the integration in composition of theoretical and psychoacoustic properties of pitch and duration; its aims are essentially practical in showing how cognitive research can inform composition, but it also addresses more broadly the value and role cognition can have in the current musical compositional climate. Various contexts for this exploration are discussed: the mediating role analysis has within theory and composition; constraints imposed by aesthetic positions and music theory/pedagogy templates; the role of cognitive psychology in connecting music templates and listening experiences; and the ultimately mythopoetic (Cook, 1992) rather than scientific nature of any such theory/psychology integration. Using Huovinen’s “pitch constellation” approach and Lerdahl’s theory of tonal pitch space, a hierarchical pitch-space is set up for the string piece ed erra l’armonia, developing from pc set 5-22 a non-standard octatonic scale (pc set 8-27) as the basic pitch collection of the piece. Similarly, using the works of Fraisse, Hasty and London, a hierarchical rhythm-space is set up for the orchestral piece Pneuma developing, from the indifference interval in duration, the temporal and metric envelops and the duple and triple subdivisions of the tactus, a three layered metrical structure as the generative rhythmic template of the piece. This is contextualised against the problematic notion of metre in modern art-music. General characteristic of both spaces are discussed: redundancy according to information theory, hierarchy in relation to cognitive opaqueness, salience and association; and elaborational and permutational processes. It is argued that composition needs to bridge, in practice, the gap between music theory and psychology of music, looking beyond their often absolutist positions; that cognitive constrains in music should be seen as opportunities to work compositionally along the mind’s cognitive grains in order to maximise structural and expressive communication; and that at a time of a ‘deregulated’ musical language it is necessary to re-develop cognitive heuristics to secure the connection between compositional choices and listening experiences. Three principles are given as guidelines for the alignment of theoretical and cognitive issues in composition. It is proposed that cognitive analysis should be developed as an independent discipline as well as a compositional tool, and that the connections style/cognition should be looked at more closely to gain a more unified perspective on diverse (and divisive) stylistic musical camps.

An original composition in three movements for large orchestra. Following the score is a detailed analysis of the work, consisting of an introduction, three sections of analysis devoted to each of the three movements of the composition, and a short conclusion summarizing the analysis.
