Hi Ron et al, Let's set up some standards so we are all sure we are measuring the same things. I would submit that we can use *proper* real time analysers from the posting I made from that thesis. Failing that, we should measure each partial *atleast* five times and throw out the high number and the low number, then average the results. And measure the atleast the first six partials. Obviously the measure devices we have are pretty crude. The piano should be a decent quality instrument. Strings should be seated on the bridge just before the unison is tested, and the strings level and hammer mating done. I believe we should try to measure the first 12 partials if using the *correct* real time analyser software. Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.M.T., R.P.T.
