By now, most people know about the incredibly strange condition called “synesthesia,” which is when someone’s senses are crossed. For instance, when they eat a red skittle, it may taste like cherry, even if it didn’t actually have a flavor. Some people can feel colors with their eyes closed. For Elisabeth Sulser, her sight, hearing, and taste have been mixed, allowing her to see colorful sound waves and taste music. Assuming that this was a normal thing, she had been living her entire life thinking other people could also taste and see music and sounds. However, when Sulser realized no one else had these capabilities, she felt alone because she couldn’t share what she was feeling with anyone. Synesthesia isn’t all good, though. People who can see sounds are constantly distracted in noisy areas and—as you can imagine—get headaches quite frequently.

Luckily, Sulser is a musician, so these abilities help her out significantly, letting her form symphonies and melodies out of colors. While still a mysterious condition, Sulser’s synesthesia doesn’t seem to have any adverse affects, especially since she only sees music (instead of regular sounds).
