This is a problem when doing touchups at intermission. Even if nothing is very far out, if enough strings have moved _just a little_ where do you put your patches? If you pluck across the three strings, and two are in tune with each other and the third is flat, you can pull up the third, and then check an octave, and also check fifths and fourths up and down. If all three are at different pitches, it gets harder. Still, the supposition is that the lowest string is out. One has to depend more and more on how an individual string fits with what's left of the tuning. Luckily even a rough player who likes to poke hard at the keys seldom makes such a hash of a tuning. Then there's the question of whether whole sections have shifted, due to bright lights, or whatever. I suppose someone using an ETD has a decision to make at this point -- reset the machine? There's not time to retune the whole thing. Susan -------------- next part -------------- An HTML attachment was scrubbed...
