We introduce the use of weighted medial graph struc- tures to represent sounds and musical events. Such structures permit the building of hierarchical neighbor- hood relationships (symmetries) while mapping time to a weight (of a note, or event). This is useful to re- late perceptual organisations (groupings in the sense of Gestalt theory) both visually and aurally. We treat time in a cinematographic way, effectively using a space- time representation. The use of colour, modulation (of waveforms), orientation, speed, etc., allows us to integrate multiple musical features in our dynamic dia- grams. We provide illustrations, including animations, of our ideas.
