At the time I was teaching composition and experimental studies in the music department at the University of California at San Diego. My Sonic Meditations flew in the face of traditional harmony and counterpoint and also of the complex written scores of contemporary music. My interests turned to the field of consciousness and the study of attention. I needed support for my work that was now where evident at the time in music theory and proactive. Listening involves the direction of attention.
Focal attention is harp and clear.
Global attention is warm an fuzzy - the two modes work together as expansion and contraction. I recognized in his talk on attention elements that supported my work. He was trying to describe human attention as a theoretical physicist. I was trying to describe listening as a composer musician. Though our respective languages were vastly different we managed through listening to each other to collaborate by sharing our discoveries for the next ten years as I created more and more Sonic Meditations and Lester described attentional processes with complex mathematical calculations.
