The sound of an English country garden on a Sunday in summer.
This is a composite of several sounds all of which must be quiet or distant enough to not be a distraction but which in conjunction are glorious:
- the sound of the breeze through the trees
- childrens’ laughter just far away enough to not be bothersome
- bees buzzing from flower to flower
- a propeller-driven light aircraft from a nearby aerodrome (ideally this would be a vintage plane with a Merlin engine, lazily warbling in the distance)
- the sound of leather on willow, and the occasional call and muted cheer, from a cricket match on the village green
- the gentle burble of a stream
- church bells, far enough away that their individual peels almost blend into each other
- the clink of ice as someone pours a perfect gin and tonic.
I went to an isolation float tank once where you get to choose the sounds/music you hear at the beginning and end of the session. I chose “Alpine meadows” that had bees buzzing, light wind moving in trees and grass and little bells chiming and it was my favourite part of the experience, I could have listened to that the whole hour. What you described is very similar and would make a great soundscape for situations like that!
