Quantitative Analysis of Non-Obvious Performer Gestures
Marcelo M. Wanderley

This article presents quantitative results from movement analysis of
several clarinet performers with respect to non-obvious or ancillary
gestures produce while playing a piece. The comparison of various
performances of a piece by the same clarinetist shows a striking
consistency of movement patterns, as well as performances of the same
piece with different expressive characteristics. Different clarinetists
show different overall patterns, although clear similarities may be
found, suggesting the existence of various levels of information in the
resulting movement. The relationship of these non-obvious movements to
material/ physiological, structural and interpretative parameters is
highlighted, providing evidence that these movements are an integral
part of the musical production process.
