Stone is undoubtedly one of the world's leading authorities on contemporary music notation and its problems. As head of the Index of New Musical Notation, he collected and categorized the myriad new devices appearing in published music of this century. In collaboration with professional performers and conductors, he evaluated these devices in order to determine their effectiveness in practical application. At the International Conference on New Music Notation 1974, a consensus was sought from the eighty participating musicians from eighteen different countries. The results have been incorporated into this volume in the clearest and most direct way. Traditional notation is given detailed treatment, constituting, as it does, the basis for many of the innovative devices. The book is organized to facilitate the location of specific information and for easy reference. A minutely detailed index is provided as an additional and indispensable tool.
