Introduction
To the aims of investigating the automatic music performance, that is in computing gestures and
controls and in transmitting them to sound synthesis equipment [Roads, 1985], we pursue an approach
that is cognition-based, and relies on a physical model in order to define a strict relationship between the
score in input and the sound produced.
The music performance process involves several representational levels [Moore, 1990], such as
physical, perceptual, operational, symbolic, structural. Consequently, a performance environment should
be concerned at least in:
i) getting a score in input (symbolic level),
ii) analysing it, like a human performer would do (structural),
iii) modelling the constraints posed by body-instrument interaction (operational),
iv) manipulating sound parameters (physical).
It should be pointed out that passing from the symbolic level to the physical level requires filling a gap:
while the first one specifies some notes to play, the latter one provides the actual gestures that an
executor would perform. While there exist some satisfactory solutions at level iv) (e.g. in the case of the
