This thesis concerned the design and implementation of an extensible computer language for microcomputer users. The language was shown to provide a minimal set of features which can be extended toward particular applications. The interactive nature of the language was discussed, along with a description of each language feature.Also presented were implementation specifics involving the use of a technique called threaded code. Motivations for the use of extensible languages were discussed, along with suggestions for further extensions and applications. / School of Music

Mawson is a piece for computer realized quadraphonic tape, and Mertz is a duo for clarinet and horn. The pieces were written in celebration of the accomplishments of the 1911-1914 Mawson Antartic Expedition. The compositions are totally serialized, with a hexachord derived from Cartesian coordinates of Antartic locations used as source material. This hexachord was rotated and cyclically transformed to control attack, rhythm, pitch, and dynamics.Performance materials can be obtained from the Electronic Systems for Music Syntheses studio at Ball State University. / School of Music

Laptop performance---performance on a standard computer system without novel controllers, usually by a solo musician---is an increasingly common mode of live computer music. Its novelty is diminishing, however, and it is frequently described as being uninteresting. Laptop performance often lacks the sense of effort and active creation that we typically expect from live music, and exhibits little perceivable connection between the performer's actions and the resulting sound. Performance software designs tend to constrict the flow of control between the performer and the music, often leading artists to rely on prepared control sequences. Laptop performers become "pilots" of largely computerized processes, detracting from the live experience. / This thesis project presents an alternative software interface that aims to bring a sense of active creation to laptop performance. The system prevents the use of prepared control sequences and allows the live assembly of generative musical processes. The software resembles a freehand drawing interface where strokes are interactively assembled to create looping and cascading animated figures. The on-screen animation is mapped to sound, creating corresponding audio patterns. Networks of strokes are assembled and manipulated to perform music. The system's use of freehand input infuses the music with natural human variability, and its graphical interface establishes a visible connection between the user's actions and the resulting audio. / The thesis document explores the above issues in laptop performance, which motivated this research. Typical examples of performance software are presented, illustrating the interface design patterns that contribute to this situation. The thesis software project is presented, describing its goals, design and implementation. The properties of the interface are discussed in light of the project's initial objectives. It is concluded that the system is a solid step toward a novel approach to laptop performance software.
