You're right there Hope, but it seems to me to be an extension of the idea of magic being word based.
Songs of power/ words of power/ spells. It's all the same idea.
But further than that, many religions also.
St John's Gospel starts with "In the beginning was the word....." for instance.
It must be nice to feel like a disembodied sound coursing through the universe, though. I envy you.
