Motivation, Microdrives and Microgoals in Mockingbird

This paper is a work-in-progress report about Mockingbird, an intelligent musical agent (IMA) based on Sun's Clarion cognitive architecture (Sun 2003). In the first part we present the Clarion architecture and the manner in which its Motivation Subsystem models drive states and goals. In the second part we propose a potential structure for modeling fine-grained secondary drives in the context of a free improvisational performance.
