2002: The Importance of Parameter Mapping in Electronic Instrument Design

The use of live electronic processing to extend, modify or transform an acoustic musical instrument has its roots in the recording and broadcast technologies that were developed in the first few decades of the twentieth century. In the second half of the century these tools were adopted by composers and musicians in many musical genres and have become commonplace and in some musics, ubiquitous. The perceived musical relationship between instrument and its electronic ‘other’ has been discussed largely from the point of view of listener and composer. This paper focuses on the performers’ perspective through reflection on and discussion of the author’s working methods in improvising duo contexts. The author suggests ‘estrangement’ as a term to describe and understand aspects of the performer’s experience of live transformation and discusses how this estrangement might influence the relationship between musicians and the resulting musical interaction in improvisation, and finally offers ‘co-estrangement’ as a description of his shared experience in such improvising duos.

Mapping transparency through metaphor: towards more expressive musical instruments

We define a two-axis transparency framework that can be used as a predictor of the expressivity of a musical device. One axis is the player's transparency scale, while the other is the audience's transparency scale. Through consideration of both traditional instruments and new technology-driven interfaces, we explore the role that metaphor plays in developing expressive devices. Metaphor depends on a literature, which forms the basis for making transparent device mappings. We examine four examples of systems that use metaphor: Iamascope, Sound Sculpting, MetaMuse and Glove-TalkII; and discuss implications on transparency and expressivity. We believe this theory provides a framework for design and evaluation of new human-machine and human-human interactions, including musical instruments.

Approaches to creating interactivated spaces, from intimate to inhabited interfaces

and bertbon@xs4all.nl In contemporary music and arts practices the previously distinct roles of author, composer and performer have become increasingly conflated, catalysed by the use of computer technology. Newly combined roles of composer and performer that are assumed by one or more people or computer systems are identified and described, as well as actions including preparation, organisation and presentation. In this paper the interface is described as an 'interactivated space' to encompass both the intimate scale of a performer manipulating the materials through an on-body interface, and the larger in-space interface where the work is shared with the performers and audience. Two examples of projects the authors are involved in are described, which form the basis for further discussion. The two interfaces that manifest themselves in the processes, the instrument and the score are discussed in more detail with a focus on their changed appearance and role.
