Precedents

There was an art installation by a CMU alum Terry Boyd. A part of the installation involved getting a tattoo - once a visitor picks the size of the tattoo they desire, and about where they want it on their body, the artist draws a random shape on the visitor's skin while telling them to think of the most meaningful memory. Once the artist has done drawing, the tattoo artist comes over and traces over the drawing with ink. 

I wanted to do something similar, but with a different medium - a music. I wanted the customized audio for the users to embed their memories and for them to be able to visit back their memories whenever they listen to the audio.
