Okay, so imagine you are at a carnival parade in a Caribbean island, and there's a person on a float or on the street with a mic and singing happy, upbeat songs that make you want to dance and sing along. That person is a calypsonian! They are like the singers of the carnival, and they usually sing about things that are happening in their communities, like politics, love, and social issues. Sometimes they use funny or clever wordplay to make their point, and they always have a catchy tune that gets you moving. So basically, a calypsonian is a singer who loves to have fun and share their joy and culture with others!
