Using Chaos to Generate Choreographic Variations
Elizabeth A. Bradley, Joshua Stuart · 1997
We describe a method for introducing variations into predefined dance sequences using a chaotic mapping. A symbol sequence representing a dance piece is mapped onto a chaotic trajectory, establishing a symbolic dynamics that links the dance sequence and the attractor structure. A choreographic variation on the original piece is created by generating a trajectory with slightly different initial conditions, inverting the mapping, and using special corpus-based interpolation schemes to smooth any abrupt transitions. Sensitive dependence guarantees that the variation is different from the original; the attractor structure and the symbolic dynamics guarantee that the two resemble one another in both esthetic and mathematical senses. 1 Introduction This paper describes a chaotic mapping technique that creates choreographic variations. A sequence of special symbols representing the body positions in a dance piece is mapped onto a chaotic attractor, establishing a symbolic dynamics that links...
