I would imagine there was some of that going on in the ancient courts of China, too. The power of musical vibrations was so important to them, that tuning of instruments was mandated each year, in accordance with wahtever key was considered auspicious for the entire country and its people. It is my understanding that all musicians were expected to comply.

Interesting question, MTed, hang in there, some of us will get serious about it and then watch out! It's gonna be even more interesting!
