Previous approaches to Common Practice Period style automated composition --- such as Markov models and Context-Free Grammars (CFGs) --- do not well characterise global, context-sensitive structure of musical tension and release. Using local musical expectation violation as a measure of tension, we show how global tension structure may be extracted from a source composition and used in a fitness function. We demonstrate the use of such a fitness function in an evolutionary algorithm for a highly constrained task of composition from pre-determined musical fragments. Evaluation shows an automated composition to be effectively indistinguishable from a similarly constrained composition by an experienced composer.
