perpetual frontier
a great book by Joe Morris
Perpetual Frontier / The Properties of Free Music describes the way free music is constructed through the processes of synthesis, interpretation, and invention. With descriptive sections of four seminal methodologies Unit Structures, Harmolodics, Tri-Axium Theory, and European Free Improvisation, as well as sections on how specific properties are consistently used and re-formulated in the construction of free music. This material, which the author developed through years of performing and teaching, is concise and coherent, making it clear for listeners and musicians alike, and thereby setting a new standard for the understanding and study of the most inherently forward-seeking musical form of our time.
