So, it's been quite a day for Hadrian's Wall of Sound.
Starting in Bowness-on-Solway and travelling the 73 mile length of the wall, the event has brought together hundreds of people and communities.
As part ofBBC Music Day, we've had unicyclists, opera singers, harpists and amateur bands. You can catch up on all the best photos from the day here.
It has been an amazing experience. From all of us at the BBC in the North East and Cumbria, thank you for taking part and sharing in it.
