John Cage's book is designed according to his music of Empty Words which is is one of his most sustained and elaborate moves toward the “demilitarization” of language, in four parts: Part I omits sentences, Part II omits phrases, and Part III omits words. Part IV, which omits syllables, leaves us nothing but a virtual lullaby of letters and sounds.The abstract design with the use of lines makes the information I added in the book to be poetic the same way that’s created by his performance.
