At some point, the tensions of the string segments between the pin and agraffe will have to be reconciled with the tension of the speaking segment and back torque and spring of the tuning pin. Either the tuner does it during the process, or time and physics takes care of it shortly after the tuner leaves. Back scale too, but that's the job of test blows, rather than hammer technique. >What to do? Which procedure is faster/better? > >Mike Spalding I'd say that either approach is better if it is the one that works best for that individual. As for faster, again, whatever fits the individual's technique(s) and gives them an acceptable (to them) balance between speed and quality. There just isn't any way that a string pulled to pitch without setting string and pin is going to stay there for long. Correction, there is one way. If the spring imposed upon the pin while the string is being raised in pitch is such that it serendipitously nearly exactly compensates for the back torque when the pin is released, it will work. I've played with this some in verticals and, while I found it interesting and entertaining, I'd hate to have to count on it for solid tuning. Ron N
