EXPORING NEW COMPOSER/PERFORMER INTERACTIONS USING REAL-TIME NOTATION
Christopher McClelland, Michael Alcorn · University of Michigan Library Repository · 2009
Composers of live and interactive electronic music have found methods of creating an integral relationship between the acoustic sound of an instrument and the electronic sounds produced using technologies.In such a relationship, sound is passed from performer to computer and is manipulated by the composer.One feature of interaction that is missing from this relationship is the potential for the composer to provide instructions to the musician during the performance.This composer-performer interaction opens up a unique set of possibilities.For example, simple alterations to the dynamics in the score can be made in real-time, or detailed rhythmic and pitch patterns can be created in real-time, disseminated across an ensemble.Simple display of information can be achieved using applications such as Max/MSP Jitter, PureData and Supercollider.However, these programs cannot support the complex notational systems required by modern compositional techniques.This paper provides an overview of the main components of a real-time notation environment (eScore), focusing on those points that are related to composer-performance interactions, specifically notation and display.Related tools and techniques, and exemplar projects are discussed as a basis for its development.
