I came across this article and wondered if there was a connection to your THE SPELLSONG CYCLE Series. If not then you may find this take on Archaeoacoustics interesting.

No, there’s no direct connection to that finding. My speculations come from a more direct source — being married to an opera singer and director and seeing the effect that music can have on people. Also, from various other archaeological observations on structures, not to mention how societies and rulers have employed music as a tool for affecting their people.
