James Tenney 
From Scratch [EPUB ebook] 
Writings in Music Theory

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 arranges, edits, and revises Tenney’s hard-to-find writings into one indispensable collection. 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.
