Ok, let's try a simpler demonstration. You strip mute a piano that's flat enough to need a pitch raise. You go up to some note in the killer octave or above. You tune it up to pitch, not pounding it hard. Then you whack it a couple of times real good. The pitch very often drops, sometimes by a couple or more beats per second (depending on how far you pulled it up to pitch). That's one lone string, all by itself, and the pitch drop comes from the back scale. Ron N
