ABSTRACT
It is reasonable to assume that the gestural characteristics of a musical performance were conveyed by dimensions of sound-space other than pitch. In lattice-based musical practice, pitch is constrained to manifest itself on the steps of the lattice defined by the system. Although musical practice constrains melodic gestalts to notation on lattice pitches, performance practice would suggest that melodic contour has something to do with the expression of gestural energy through pitch-motion. Language use suppresses the gestural implications of the stress and inflection patterns used. A more complex and highly-articulated development of the concept of seamless divergence and merging of sonic streams was proposed and this would certainly be an entirely new realm of musical development dependent on our acceptance of the multi-dimensional continuum as a valid substrate for physical composition. The chapter also describes four distinguishable gestural types which were applied to the gross characterisation of a sound-event.
