Rhythmic Perspectives: Creative explorations in composition and performance practice on the double bass in response to cognitive theories of rhythmic perception

This research examines techniques for the manipulation of rhythmic perception in the creative practice of a jazz composer/performer. Utilising both practice and research-led methodologies, the thesis documents new applications of interdisciplinary research to the development of five new creative works and corresponding developmental processes on the bass. The works seek to engage different components of the human cognitive system and enculturated experiences to generate unique rhythmic frameworks and groove experiences. The thesis contextualises relevant research pertaining to historic discussions of rhythm and groove in musicology, cognitive understandings of brain processing centres and memory used in rhythm perceptions. It explores the role of enculturation and a framework for the relationship between cognitive process, action, and resultant sound in music. The five works examine the engagement of echoic or precognitive sensory perception in the listener and performer through subdivision: rhythmic frameworks for alternate metric entrainment relationships within the short-term memory processing range, and an examination of the perceptual limitations and enculturated behaviours shaping our listening experiences. As a practitioner-focused study, it includes high-resolution analysis of developmental process on the double bass to assist the enculturation of new rhythmic practices and realisation of the resultant works
