Abstract [en]

This chapter examines computer assisted analysis and composition (CAAC) techniquesin relation to the composition of my piece TreeTorika for chamber orchestra. I describemethods for analysing the musical features of a recording of a speech by Mao Zedong,in order to extract compositional material such as global form, melody, harmony andrhythm, and for developing rhythmic material. The first part focuses on large scalesegmentation, melody transcription, quantification and quantization. Automatic tran-scription of the voice was discarded in favour of an aural method using tools in Amadeusand Max/MSP. The data was processed in OpenMusic to optimise the accuracy and read-ability of the notation. The harmonic context was derived from the transcribed melodyand from AudioSculpt partial tracking and chord-sequence analyses. The second partof this chapter describes one aspect of computer assisted composition, that is the useof the rhythm constraint library in OpenMusic to develop polyrhythmic textures. Theflexibility of these techniques allowed the computer to assist me in all but the final phasesof the work. In addition, attention is given to the artistic and political implications ofusing recordings of such a disputed public figure as Mao.
