One of the twentieth century's most important musical thinkers, James Tenney did pioneering work in multiple fields, including computer music, tuning theory, and algorithmic and computer-assisted composition. From Scratch is a collection of Tenney's hard-to-find writings arranged, edited, and revised by the self-described "composer/theorist." Selections focus on his fundamental concerns--"what the ear hears"--and include thoughts and ideas on perception and form, tuning systems and especially just intonation, information theory, theories of harmonic space, and stochastic (chance) procedures of composition.
