Dear Data - inspiration for musical notation

I was planning to create some musical notation for musicians to improvise. The idea being they record their own anxieties/feelings about music and their musical identity, record it using a formulated notation system. 

Every week for a year, designers Giorgia Lupi and Stephanie Posavec sent each other postcards charting something in their lives, for laughter to travel to phone addiction. They use beautiful illustrated infographics that could all become musical notation i would love to try and achive something along these lines and i think i should do it with myself to start!
