The author uses the sonogram to realise a structural analysis of Sud, an electroacoustic work by Jean-Claude Risset. After creating a segmentation of the piece, he describes its sound material using three categories: natural sounds, human sounds, and synthesised sounds. Three extracts of sonograms and a structural representation complete the article.
