If I understand correctly, you wish to be able to determine the tension on strings in a piano? Just measure the diameter of the string, measure the speaking length, measure the pitch, and calculate the tension.

My reason for asking is that recently I have been hearing from our local Steinway dealer about the low tension scales on Steinway grands and the higher tension scales on Yamaha's. I have believed in the past that Steinways had higher tension scales and that was a big reason why they are loud pianos and strong in power as compared to Yamahas which seem to have a sweeter, more airy sound. Likewise the European pianos. I always associated low tension with this airy, sweet sound. It appears that I may have been wrong in having this opinion. I was thinking there was some way to empirically gather info on the amount of inharmonicity a group of selected notes on the piano would have and interpolate from there where the tension would be. I guess it is not as simple as that. This, however, also clouds the air as there is no way to tell individually the overall tension on a scale by just taking some inharmonmicity readings.. I guess there is no way to uncloud claims of dealers or manufacturers. Thank you for your help.
