A harmonica is a small musical instrument that you can hold in your hands. It looks like a little rectangle, kind of like a small chocolate bar! Sometimes it’s shiny and colorful, with holes on the top where you blow and draw air.
When you blow into the holes, it makes a happy sound, like music! Some harmonicas are all one color, like blue, red, or yellow, and others might have different colors on each side. So, it’s not only fun to play but also pretty to look at!
You can play a harmonica by moving it back and forth while blowing air. Just remember, it’s very small, so you can easily hold it with your little hands!
