In this article we report on progress at the Australian CRC for Interaction Design investigating the computational generation of orchestral music based in the Germanic Symphonic tradition. We present an introduction to the project including a brief overview of our intended methods and some guiding principles for the project. We then outline the current state of the project and introduce our initial algorithmic system with a special emphasis on an implementation of Paul Hin-demith's harmonic system. We conclude with some initial findings and future goals. We provide an extensive selection of audio examples on-line that accompany, verify and enhance information provided in this report.
