Q: (Pierre) So it means some kind of music? Perfect tunes? If you play the right notes in the right sequence... And the right combination... Music can be healing.
A: Important that the tone is accompanied by subtones and frequencies that are natural to the stone and "speak" to the cells in the body.
Q: (L) So I guess you can't just play the music.
(Pierre) No, it's more elaborate than that. But it means a great amount of knowledge...
A: Notice the specific stones chosen for Stonehenge.
Google says that Stonehenge is mainly white chalk, limestone, i.e. calcium carbonates. And also links to this article inter alia: Calcium, building block for the world.
My best wishes to all injured, please get well soon!
