As music is time base, a story needs to be written before is composed.
Inspired by Vladmir Nakobov who had color grapheme synaesthesia, the story consists of “letters”. Letters that define an object/thing/experience. For example : In the green group, there are alder-leaf #f, the unripe apple of #e, and pistachio #a.
Each letter eventually evokes a visual treatment based on the story.
