Elaine Walker is a composer, electronic musician, mathematician, and author born in 1969. She wrote a physics/philosophy book, “Matter Over Mind: Cosmos, Chaos, and Curiosity” (2016). She specializes in microtonal music, including founding ZIA, an all electronic band, and performing with D.D.T. She has performed with Number Sine. She describes: "I compose microtonal music strictly by ear and leave it to others to analyze, so you won't find ratios or mathematics here."
