Synethesia - Not Just a Disorder Anymore

I am currently reading a biography of Georgia O'Keeffe and finding it interesting, though rather dense. In the book, the author discusses how O'Keeffe, when she was learning to paint (perhaps later - I haven't gotten that far yet), would listen to music and paint the music.
This is called synesthesia. Synesthesia is actually a disorder that has far-reaching consequences, but we can incorporate a little of this into our own life.
I was imagining an exercise where we listen to music and try to write down what we hear. This would not be about lyrics but sounds. I often use music as a background when I'm writing my blogs, but I rarely make it the main focus.
As we have discussed before, exposure to any kind of art is important to stimulating creativity. This would be just another way to incorporate this into our lives. Personally, I think anyway to have a more musical life, is a good way.
