In this paper we present an interactive two-dimensional
representation of musical chord progressions, integrated
into a computer program that generates house music harmonic
loops in MIDI format, based on a user’s input. Our
aim is to encapsulate relevant tonal information and display
it in ways that are easy to understand for novices and
untrained musicians, facilitating the creative exploration of
musical ideas. We briefly reference previous work on tonal
visualisation and interaction, and introduce some measures
of tonal properties from the literature. We then present our
system and describe the two-dimensional harmonic map,
before discussing its outcomes and shortcomings, pointing
at future lines of research in the conclusions.
