>> Pianist at MIDI keyboard with computer, 2m30s

Each section of this typical march form (first strain, second strain, trio) showcases a different aspect of the thirteen-tone environment. I was especially interested in creating an interplay between elements that sound similar to standard tuning and those that sound foreign. For more information, please read this essay on my microtonal works, which features an anaysis of the march.
