[pianotech] Stability techniques

[David Love]

I agree with some previous comments that stability comes from hammer technique more than from pounding technique. In fact, excess pounding can be counter productive. I find that reaching the desired pitch from below rather than pulling it sharp and pounding it down is better. To do that requires a flexing of the pin down toward the plate from a 12:00 to 1:00 hammer position to offset the twisting so that the string movement is minimized. A relaxing of the flex concurrent with the relaxing of the twist leaves the pitch unmoved (if done correctly) and less differential in the string segments to move later which is the main source of instability.

Most of the Ds I tuned were from Hamburg . The sequence I learnt was to 'play, hear, tune, test blow and listen for best tone. How hard to pound depends on the pin condition. The usual note to trick me is F# 82 .
