Evolution Of Musical Organisms, Bruno Degazio
Publications and Scholarship
The development of software for musical applications has led to a proliferation of elaborate control paradigms with extremely large parameter spaces. These spaces can be daunting to explore interactively because of their vastness. Furthermore, parameters often interact in ways not made explicit by the control panel, effectively increasing the complexity of the space even further. Application of genetic algorithms (GAs) can be used to search through these vast spaces in a highly efficient manner. Coordinated control of interacting parameters is handled automatically by this system. Even for control paradigms that are well understood, the genetic algorithm can efficiently search out …

A Computer-Based Editor For Lerdahl And Jackendoff's Rhythmic Structures, Bruno Degazio
Publications and Scholarship
In “A Generative Theory of Tonal Music”, Lerdahl and Jackendoff discuss two forms of rhythmic structure which they call metrical structure and grouping structure. Together these constitute a basis for an analytical understanding of rhythmic structure in music. This article is about a software based editor which allows the interactive exploration of these two types of hierarchical rhythmic structures.
