The eyes look, and the eyes read. I propose they can also listen – an act different from both looking and reading. To explore this possibility, I have put together a book of non-linguistic, non-pictorial visual material: Seesongs. The drawings in this book are progressions of visual marks, which could be called asemic music/ notation.
