Our ongoing research in performance theory integrates methods for complex instrument parameter spaces and models for musical gestures. The latter are modelled as parametric curves residing in high-dimensional symbolic and physical gesture spaces. This article shortly exposes basic concepts of those spaces and the construction of symbolic gesture curves. It then discusses the problem of fitting physical gesture curves (which are based on their symbolic counterparts) as a function of anatomical and Newtonian constraints. Our solution makes use of Sturm's zero theorem for cubic splines. The resulting curves can be applied to animation of avatar parts in an animation system. This theory is implemented in the latest version of the performance component of a well-known modular software for analysis, composition, and performance.
