A software system for laptop performance and improvisation /Zadel, Mark. January 2006 (has links)
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.

On the design of extensible music authoring toolsRaghu, Vamshi. January 2007 (has links)
The past half-decade has seen progress in methodology and reusable components available to designers of music authoring tools. This thesis examines currently prevalent architectures for music making software and applies currently available technical means to update design methodology and architectural patterns for the next-generation of tools. It aims to map the various categories of advances and the manner in which they relate to each other, to the problem of building these tools. The focus is on conceptualization. The thesis aims to understand, from historical perspectives, as well as from perspectives provided by other domains, the fundamental problems encountered in the process of designing authoring tools. / Issues examined include building rich visual and interactive interfaces for authoring, the use of multiple notations and formalisms to describe multiple aspects of musical structure, end-user extensibility and end-user script ability. The results of design experiments implementing core ideas are documented, and the manner in which the ideas from these prototypes may be applied to the construction of real-world tools is discussed. As far as possible, the thesis investigates existing tools, frameworks, design ideas, and architectural possibilities that scale. In conclusion, the manner in which the investigation relates to the future of authoring tools, and to problems faced by contemporary artists and tool-makers is discussed.

Computer generated music : a methodology for computer music compositionTibbetts, Tracey D. January 1999 (has links)
This study will prove the fact that computers provide unprecedented opportunities to create music. Several distinct levels of computer participation can exist in the creative process. The lowest level, involving record-keeping functions, results in programs that serve as compositional aids. The intermediate level incorporates stochastic (literally "random") processes on a limited basis, and represents the midpoint between computer-assisted and computercomposed works. The highest level focuses on the design of algorithms that result in compositions determined in most of their details by stochastic processes and computer decision making. Although there is no clear dividing line between levels of computer/composer interaction, it is possible to characterize the degree to which the computer has provided outcomes for a given work, from low-level random generation of pitches to high-level Markovian chain distributions. / Department of Computer Science

Interactive multimedia composition on the World Wide Web : a solution for musicians using JavaBeaulac, Jacqueline. January 2000 (has links)
This thesis attempts to gauge the strengths and limitations of the Java programming language in terms of its use in the production of multimedia compositions: in particular, the ways in which Java supports the creation of interactive, non-deterministic musical works. An original solution to the problem of multimedia design is presented: a hierarchically defined, basic, yet flexible scripting language that is interpreted using Java. This scripting language allows the user to incorporate his/her own media into a coherent and interactive form using a small set of simple keywords and basic operators. It also allows new functionality to be added by advanced users with a basic knowledge of Java. By investigating how such a scripting language may be implemented, the extent to which Java may be applied towards multimedia applications in general is revealed.

Rule-based expert systems and tonal chord classificationJanidlo, Peter S. January 1999 (has links)
The purpose of the proposed thesis is to:1. Define expert systems and discuss various implementation techniques for the components of expert systems. This includes discussion on knowledge representation, inference methods, methods for dealing with uncertainty, and methods of explanation. Specifically, the focus will be on the implementation of rule-based expert systems;2. Apply selected expert system techniques to a case study. The case study will be a rule-based expert system in Prolog to recognize and identify musical chords from tonal harmony. The system will have a general knowledge base containing fundamental rules about chord construction. It will also contain some knowledge that will allow it to deduce non-trivial chords. Furthermore, it will contain procedures to deal with uncertainty and explanation;3. Explain general concepts about music theory and tonal chord classification to put the case study in context; and4. Discuss the limitations of expert systems based on the results of the case study and the current literature. / Department of Computer Science

Portfolio of compositions and exegesis: conflict and resolution - modelling emergent ensemble dynamics.Harrald, Luke Adrian January 2008 (has links)
Theory as an approach to generative composition and interactive computer music. Inspired by the notion of Performance Indeterminacy, software has been developed that attempts to simulate the interactions of improvising performers using a multi-agent system based on the ‘Iterated Prisoner’s Dilemma’. Composition activities and programming activities have formed a symbiotic relationship throughout the creation of the portfolio as each has constantly informed the other. Stylistically, the works presented fall into the experimental genre, although individually they address a wide range of aesthetic goals. The main contribution of this portfolio is a new approach to generative composition based on behavioural models, creating a sense of form bottom-up through modelling the social dynamics of music performance. Through this approach, the direct modelling of musical structures is avoided; instead larger scale forms emerge through the interactions of an ensemble of ‘improvising’ agents. This method offers a departure from previous complex systems work in the area of music, creating computer models of specific musical situations. Links between the Iterated Prisoner’s Dilemma and music are also established and combined with current music technologies. / Thesis(Ph.D.)- University of Adelaide, Elder Conservatorium of Music, 2008
