Maddie listens for sounds and hears that they’re everywhere. She learns sound can be very high and very low, she asks - How does sound reach our ears? Do you know? We learn sound is a vibration it is something that shivers, quivers, shudders, judders, wibbles, wobbles – it vibrates! A vibration is invisible, but Maddie tells us how we can feel sound vibrations in our throats when we sing, or see them on a drum when it bangs.
