Designing a creative AI system or performing on an intelligent instrument is a particular mode of operating, a unique approach of framing musical and interaction problems and solutions. The paper introduces the idea of constrained writing, gives a philosophical background to the paper and its methodology, and then announces an assemblage of analytical concepts that can be used to assess AIMC systems as we encounter them for study and evaluation. A constrained defining lexicon of A.
