The following animated software simulations demonstrate some of the ways Harmonic Interference Theory can be applied to music composition and analysis tools. You will need Flash 7 or higher installed on your computer to play them.

Two-Dimensional Dashboard

This animation simulates how some of the models discussed in the book would look when used together in a computer-assisted music analysis and composition system. The models used include the harmonic lattice, the REFLECTIVE INTERFERENCE model (both linear and polar), the Chromatic Ring model and the Dual Chromatic Ring model. Together, the models help measure the tension and resolution of the example song fragment, including an average measurement of its "ethos" or psychoacoustical anticipation/ reward potential. Beyond the metric application, the beauty of music expressed as geometry and colors is an art in itself and reason enough for such an application.

Note: This is only a simulation. The only interactivity is to play, pause and step the animation using the small control panel at the top.

iPhone Dashboard

One of the viewpoints expressed in the book concerns the application of Harmonic Interference Theory to mobile Internet devices.. In this example, a simple prototype is given for this purpose, though a 3-D view of musical objects flying into the screen would be another possibility.

If you want to see how this plays on your on iPhone, just right click the video file link here and save it your desktop, then drag the Dashboard.mp4 file into your iTunes video section to synch up and install on your iPhone for playback. When you play it, it will look and sound just like this prototype.
