Timbre is a musical attribute that has been largely discussed among the research community. However, there is still a lot to investigate, especially in regards to timbre and orchestration, which involves polyphonic timbre: a phenomenon that emerges from the mixture of instruments playing simultaneously. In this paper, we report on the development of a system capable of automatically analysing and classifying perceptual qualities of timbre within orchestral audio samples. Here, we have decided to use verbal descriptors of timbral properties, such as brightness or roughness, in our system in order to make the tool accessible to non-acoustics experts. Furthermore, this automatic timbral classification approach has been implemented in a computing system capable of generating orchestral compositions based on the timbral properties contained in audio files input by the user. Our rationale for developing such a system is to create a means of incorporating musical timbre in the composition of music, which is often focused mainly on traditional Western music theory (i.e. pitches, chords). Such developments could enrich creative music systems and aid composers in their metier.
