Try vibrations.
The look on a child's face when in the proximity of real vibrations is astonishing, every time.
The other day, as I improvised together with a four-year-old, I was intensely aware of his quiet connection with the sounds we made together. He was imparting a secret, all the more real because it was not prefabricated and because it certainly could never happen again in exactly the same way.
What a revelation as to the nature of musical intimacy: how it works and why it works.
