Our ancestors knew so much more than we do now.
Stonehenge is one of the most famous of these sites but there are many world-wide that had multiple uses. One of those being, making these stones sing in tune to the local conditions.
This profound knowledge would have been taken forward to the construction of buildings. Especially cathedrals.
I’ve been inside huge cathedrals listening to just voices sing. This sound produces feelings and physical sensations in our bodies that uplift us into a state bordering on euphoria.
Beautiful :o)
