Hundreds of children all over the country are taking part in BBC Music Day today.
The day is a celebration of everything people love about music.
There are live performances and events happening in towns and cities all across the UK.
George Ezra, Pixie Lott and Mark Ronson are all ambassadors for the big day.
Kids from Liverpool are singing, dancing and doing body percussion - that's making music just using their voices and bodies.
