I’m jealous of synesthetes, damn it. I wish I could see colors along with music, but I’ve always visualized music as shapes. Not like circles and squares, though — more like waves, ripples, snaking lines and expanding dots. In fact, it’s kind of like a mix between sheet music and those psychedelic screens in Windows Media Player that pulse and shift in time to whatever music you’re listening to. Except without color.
I really, really wish I could get some color in my interior audio/visual experience.
