Consider a tuning fork. It delivers a true pitch by two tines vibrating together. Muffle either side, even a little, and the note disappears. Neither tine individually produces the sweet, pure note. Only when both tines vibrate is the correct pitch heard.

I could only publish a few pics in the previouse post so I am adding a few more here. These are ones from our drive through the Redwood forest. WOW, what an experience to see this.
