Listening to music is a tremendously enjoyable experience. I see sound as colors, shapes, and textures, projected onto their source. In other words, if the microwave beeps, I see a little red dot appear near the microwave. If a guitar solo plays from a ceiling speaker in a big box store, I see the little purple globules flying through the air.
With a good speaker system or headphones, the experience is greatly improved and I am literally surrounded by the sounds of whatever I’m hearing.
The colors, shapes, and textures of a sound are completely analogous to the sound itself. Every tiny change in a sound also creates a tiny change in what I see. my experience of hearing sound and seeing sound are inextricably linked; I can’t just listen to music any more than you could eat a hot pepper without tasting it.
For me, listening is seeing, and listening to music is very literally like watching animated abstract art on the most high definition screen you can imagine. Indeed, a lot of my favorite art reminds me of some of my favorite music, and vice versa.
To be clear, I don’t hear sounds when I look at art; that’s called “visually-induced auditory synesthesia” and that’s one kind of synesthesia I don’t have. (More about that here).
My synesthesia does not distinguish between “music” and other sounds; every sound that I hear is both a sound and a collection of colors, shapes, and textures. A sound will look exactly the same whether it is heard in isolation or within the context of a musical piece. (Check out the main chromesthesia page for more examples.) This is an important distinction, as some syntesthetes with chromesthesia only experience it with “musical” sounds.
For me, every sound is an explosion of color.
That’s sort of a simplistic representation of a techno track.
