Why Do Some People ‘Taste’ Music and Others Don’t?

Some people can taste music because their brain connects sounds to flavors, like a magical kind of superpower. It’s called synesthesia, and it means one sense can trigger another, for example, when you hear a song, your brain might send the message 'I taste blueberries!' instead of just saying 'this sounds nice.'

Imagine you have two magical doors in your brain. When sound comes in through one door, sometimes it slips out the other and tastes like something sweet or sour.
