Vibrations

I've been doing some thinking. And I think that certain messages, if delivered with certain sounds, intrinsically are easier to remember. Wait, that's not quite it. The messages automatically become logged and I find I have an immensely high recall of technical facts years later if I hear those sounds. This is one of them. Tibetan meditation (low range) bowls are another.
I would probably be interested in making a hang drum someday because they are so supa sweet.
