INFORMATION TO USERS The most advanced technology has been used to photo­ graph and reproduce this manuscript from the microfilm master. UMI films the original text directly from the copy submitted. Thus, some dissertation copies are in typewriter face, while others may be from a computer printer. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyrighted material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are re­ produced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each oversize page is available as one exposure on a standard 35 mm slide or as a 17" x 23" black and white photographic print for an additional charge. Photographs included in the original manuscript have been reproduced xerographically in this copy. 35 mm slides or 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge.

Special thanks are certainly due to two persons at IRCAM who helped me greatly, David Wessel and Marco Stroppa. Without the assistance of Marc Battier, Jan Vandenheede, Denis Lorrain, Thierry Lancino, and the others at IRCAM who assisted me with my research, the results of this investigation would not have been nearly as well grounded in practice. I would like to thank the members of my dissertation committee, Dr. David Butler and Dr. Gregory Proctor, for their personal interest and assistance, and for their exemplary instruction over the past years. My adviser, Dr. Thomas Wells, has given vital encouragement to my work, insight into the craft of musical composition, and a new appreciation of the music of the masters. I am glad to have had the opportunity to study and work with a musician and composer of his stature. My wife, Judy, has provided continuous positive support during the research and preparation of this document, without which its completion would not have been imaginable.
