Well said David! Interesting subject isn't it? One must not get "hot under the collar" when discussing these things for there is such a lot to learn and we won't ever learn it all - but we can try! I favour the use of one mute only technique in the general tuning of pianos. I used to use two mutes but that was when I used to tune from a tuning fork... all those aeons ago! Now I use a trusty ETD just for the bearing octave - but even so I always do a check by playing M3's chromatically so soon as the chance permits. One gets to know instinctively how fast the beats go and having learned that one goes to listening out for other intervals - M10's and M17's. I suppose one should bear in mind the inescapable relationship of the doubling of the frequencies with every upward octave. Ask yourself "If that much change occures within one octave how gradual is the change from semi-tone to semi-tone within that octave?" The answer is that it follows the curve plotted by the frequencies of the octave points. There is a mathematical equation the 12th. root of 2 (if memory serves me aright) And this is important to appreciate, for until it is understood and appreciated the importance of those beats will for ever escape you! For me these beats are my very own "invisible tool" without them I am lost and I might as well be a refuse collector (and earn good money and have no responsibilities and....and.... Gosh!) Then comes that interesting chap Virgil Smith and his Phenomenon. This is more readily appreciated by those who tune up their guitars, violins 'cellos etc. for these are wooden instruments and the effect of tuning one string can have a dramatic effect on the others. Which is why I developed my "Quadrant Method" for pitch raising (and lowering - it works both ways!) With it I use the V.S.P (Virgil Smi..) to my advantage and can pitch raise up to a whole tone in one pass and only have to touch in with a fine tune at the end. And a "fine tune" does not mean "within 2 cents" it means within NO cents - it simply has to be 100% right. Strive for that "and you'll be a man my son!"
