Audio.Visual - On Visual Music and Related Media (2009) by Cornelia Lund and Holger Lund (Eds.) is divided into two sections: the first deals with the academic discussion on the subject of visual music; the second introduces contemporary paradigms of audio-visual praxis in brief presentations and contextualises them. Apart from being a guide in the historical sense, this new volume provides theoretical approaches to understanding and making visual music. (Fluctuating Images)

Digital Harmony (1980): On the Complementarity of Music and Visual Art – John Whitney, Sr. wanted to create a dialog between "the voices of light and tone." All of his early experiments in film and the development of sound techniques lead toward this end. He felt that music was an integral part of the visual experience; the combination had a long history in man's primitive development and was part of the essence of life. His theories On the complementarity of Music and Visual Art were explained in his book, Digital Harmony, published by McGraw-Hill in 1980. (Paradise 2012)

Grid Index (2009) by Carsten Nicolai is the first comprehensive visual lexicon of patterns and grid systems. Based upon years of research, artist and musician Carsten Nicolai has discovered and unlocked the visual code for visual systems into a systematic equation of grids and patterns. The accompanying CD contains all of the grids and patterns featured in the publication from the simplest grids made up entirely of squares to the most complex irregular ones with infinitely unpredictable patterns of growth, as editable vector graphic data files.
