What's your song? What do you see while listening to it?
Everyone has images running through their minds, consciously or subconsciously as they work through the day. This sense of picturing thoughts started off as a trigger point into music as a sensory experience.
The research involved conducting various test experiments on a group of people ; drawing from music and scanning their playlists to produce sound waves. This in turn formed the base for 3D experimentation, which was pattern cutting based on the rhythmic shifts in the sounds.
