List Was tuning a Steinway C today and managed to put my finger, or ear as it twere, on something thats been bothering me for a long time. I think all this talk about pitch drop, and other string anomolies that made it finally gel. Course I cant be hundred percent sure but it sounded like there was definate drop in pitch for just one (or at least in particular) one partial for several notes in a row in the killer octave area. Let me be a bit more specific... Tuning octaves as usual, I reached C6 I think and then I noticed that playing against C5 I could definatly hear the beating of the 4:2 get faster and faster as the string energy dissapated. At the same time the 2:1 didnt seem to change at all.. Took me a second or two to define exactly what was going on but when I did I could quickly hear and identify the same thing for 10 - 12 notes in the area. So what I am wondering then is this... is it possible for this pitch drop phenomena to affect only one partial, or perhaps affect each partial a bit differently, even perhaps leaving one or more partial uneffected ? One last thing... I only noticed this affect in the so called killer octave area, tho I will pay a bit attention in the nearest few days to see if I can get a handle on this in other areas. -- Richard Brekne RPT, N.P.T.F.
