Despite having written about it twice before, it sometimes seems like a well kept secret that I have sound-color synesthesia. I do! This means that I “see” colors when I listen to music, but it also — and more importantly for today’s post — means that when I sit down to write music, I start by imagining colors, and those colors guide me to the sounds I need. Over the years that I’ve been composing, I’ve built up a pretty robust system of key-color associations, and today I’m going to provide a peek under the hood and actually list them out.
