As part of a research project at Missouri State University (EEUU), this composition in order to reveal the tone quality of chinese speech. For this purpose the pitch contours (chinese tones) of the words are extracted  (using linear predictive coding) and then either imposed on acoustic chinese instruments or re-synthesized as sine tones that coexist with the original vocal source. These vocal sources are also transformed using time varying time stretchings, spectral stretching, generation of crowd textures and different granulation approaches. The composition was made using CDP (Composers Desktop Project) and Supercollider language.
