Bass (sound)

Bass is a type of sound that makes things vibrate and feel like they're shaking. It's like when you hear a big truck drive by or when someone plays loud music that makes your tummy feel funny. Bass sounds are really low and deep, like a grown-up's voice when they're trying to be extra serious. You can't see bass or touch it but you can feel it in your body, almost like a tickle. It makes things move, like your ears and your hair. Some people really like bass because it feels like a big hug from the music.
