Aspect-oriented programming (AOP) attempts to modularise crosscutting concerns in software. Initial approaches to AOP have used static weaving techniques in which crosscutting implementation, encapsulated by aspects, is merged into . Research into dynamic aspects suggests various ways in which crosscutting implementations may be dynamically woven into code, enabling aspects to be defined and composed at run-time.

It has been suggested, in [14], that AOP might be usefully applied at the end-user level in applications that support multidimensional creative processes, and in particular, of music composition. In this paper we extend this argument to suggest that dynamic aspects are essential to this application. We motivate our argument with a high-level description of crosscutting that exists within music composition, and ways in which these crosscutting concerns, and requirements for their management, have arisen from our initial use of static aspects in music composition. We then evaluate some of the ways in which current research into dynamic aspects might be utilised in addressing these requirements.
