93kB PDF file)The "Air Worm": An Interface for Real-Time Manipulation of Expressive Music Performance
- Simon Dixon, Werner Goebl, Gerhard Widmer
- Expressive performance of traditional Western music is a complex phenomenon
which is mastered by few, and yet appreciated by many.
In this paper we explore various ways of interacting with expressive
performances using methods that are
accessible to non-expert music-lovers.
The key idea is that a non-expert cannot control the vast range of parameters
which musicians use to create expression; they require a simple interface
allowing control of a small number of parameters, where the remaining parameters
are determined by expert performances.
A digital theremin is used as an input device,
and users can control the two most important expressive parameters,
tempo and loudness, of an expressively performed audio or MIDI file.
Several modes of operation are possible: the "Air Worm"
builds on previous work in performance visualisation, where the tempo is
displayed on the horizontal axis and loudness on the vertical axis in a
two-dimensional animation;
the "Air Tapper" uses a conducting metaphor where the beat is given
by the minimum vertical point in a quasi-periodic trajectory;
and the "Mouse Worm" allows
users without a theremin to use the mouse as controller.
