This paper describes how a music theory with explanatory power for expression of relationships between pitch classes, chords and tonal regions can be exploited as the foundations for a computer-based tool, called ‘Pitch Circles’, to support musical novices learn about and manipulate such musical concepts and relationships . The paper introduces this research with a brief review of the ‘direct manipulation’ principles for computer interaction design on which the computer-based learning tool has been based, and of the features of tonal theories which led to our choice of a particular theory, ‘Pitch Spaces’, as the basis for this work.
