A graphical environment for gestural computer-aided composition

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2002.Includes bibliographical references (leaves 102-103).I have designed and implemented a software environment, a Windows application called Hyperscore, that presents a novel, easy-to-learn interface for composing richly textured music through line gestures. The program allows the user to command a set of music-manipulation algorithms written by Mary Farbood [Farbood, 2001]. The interface is both compelling and interesting for musically untrained users, and rich enough that such users, after sufficient practice, can create music that professional musicians find to be of high quality. While many musical composition programs geared for musically untrained users exist, it is its unique user interface, its use of freely drawn line-gestures, zooming navigation, and simple symbolic icons, that helps make this program unique. The program was designed to enable musically untrained children, ages ten or older, to compose three-minute pieces for a string orchestra, given only a week or so of two-hour daily workshops. The program succeeded in this, and has been presented to audiences in Berlin, Dublin, and Glasgow as a part of Toy Symphony. The program has also been made available for download.by Egon Pasztor.S.M
