''Johnston's contributions are monumental, and this collection illustrates why. Not only are the theoretical writings extremely useful for scholars, composers, and performers who want to understand just intonation, but the spiritual aspects of Johnston's writings and Gilmore's explanations are inspiring for all readers.''--Heidi Von Gunden, associate professor, School of Music, University of Illinois at Urbana-Champaign ''A most valuable and original book, Maximum Clarity gives a much clearer and fuller idea of the music and thought of a truly innovative composer.''--Charles Hamm, Arthur R. Virgin Professor of Music Emeritus, Dartmouth College
