Dear Barrie, Nope. They don't exist. In all honesty, it might just be a vicious rumor. Most of the writing I've seen regarding even the concept of constructive interaction between two string's partial segments contain wriggling words like; "...it appears that" or "...some benefit seems to be gained" or even; "...perhaps", mingled in with statements like; "further experiments in this direction might yield beneficial results..." or "..it may be found that...". Sorry I couldn't be of more help. (sigh) Regards, Jeffrey T. Hickey, RPT Oregon Coast Piano Services TunerJeff @ aol.com ps- Thanks for your 'reporting' from across the Atlantic Pond, too. This "virtual-world" brings us all a bit closer, doesn't it? jef What were we talking about? *********************************************** TunerJeff@aol.com writes > I do find that after finishing a tuning, and striking a large & friendly >chord, the freshly tuned piano often seems to have an enormous ...well... >strength to it's sound... and often carries a corresponding increase in >sustain.

Hickey, RPT >Oregon Coast Piano Services >TunerJeff @ aol.com Hi Jeffrey, That's quite an interesting theory you have there. do you know of any experiments which have been carried out to confirm this theory, which on face value seems extremely plauseable. Not to say that it matters to us as tuners which is correct tuning correct octaves or slightly stretched octaves, its what the customer requests. I must admit none of my customers have actually requested me to tune the octaves any different than what I have been doing in the past, however, on the other hand if they don't know any different I don't suppose they would ask any rode. Regards, Barrie. ********************************************************** Endit
