Wow. Thanks, Jim. Clarity is precious. I have deliberately stayed back  
in this maglollis of wackiness, but all of these words can be put to  
rest when you watch somebody who tunes with those natural beats do  
their thing. I'm working on getting a situation in Grand Rapids where  
we'll have a time when people who want to can watch me tune, all the  
way through. and then play and listen to the result, and debrief away.  
This whole-tone, natural-beat, open-string tuning is a powerful,  
incredibly valuable tool.
