I will be presenting my work in algorithmic music composition at the Cascadia Composers Lecture Series on January 13, 2020 at 7:00 PM in Lincoln Hall, Room 219, at Portland State University. The presentation will cover three main algorithms; arsNova, arsMosis, and topoNova. This suite of programs generates melodies based on the fundamental concepts of computing and statistical mechanics; Turing machine, cellular automata, and entropy. These programs are especially useful for generating fundamental melodies used in the composition of a canon or fugue. I will also cover a new algorithm that generates melodies which can evoke several emotions; sadness, fear, happiness, serenity, etc… The system uses both a symbolic AI rule-based strategy and a statistical unsupervised machine learning method acting on a population of shape grammars, where each population can be thought of as a different emotion. The shape grammar is an abstraction that defines the fundamental building blocks of a melody. A demonstration will be given on how to use these algorithms on their own as well as in combination with one another.
