Sounds I love to hear.

The sound of nature are incredible. Lots of them are very relaxing.
I like a lot of what’s already been mentioned.
Bees busily feeding.
The noise of grasshoppers and crickets.
Dragon & damselflies flying by.
The male blackbird song. Always brings back memories of my childhood.
Snipe drumming in spring, the Roaring of the deer at the rut in autumn.
Waves breaking on the shore and the noise of the gravelly beach as the water makes its way back out to sea.
Water making its way along the burns & rivers and going over waterfalls.
So many sounds that just make me stop and watch for a while. It’s amazing I manage to get anything done
