---------------------- multipart/alternative attachment Hi folks A couple weeks back an old timer told me that it was a good idea to tune up from the tenor to the low treble... say around C5, and then tune downwards from C8 for the first pass. His reasoning was that as you tune upwards you are pressing down somewhat on exactly where you just adjusted tension, and this forces the immediate area adjacent and towards the side with most crown upwards a tad. So tuning up to C5 and then down from C8 was to put this matter to good work as it were... tending to push this killer range of the soundboard upwards. Nice theory I thought, but I mean reaaalllly... So anyways.. I decide to try it out and see if I can notice anything at all and low and behold.... I notice a rise in pitch in exactly this area. First couple pianos it just struck me as things were moving around a bit unusually, then on the 3rd instrument I decided to run a quick pitch check in the middle high treble before starting the tuning, and then again before starting tuning that area... sure enough the whole section had raised in pitch. This instrument was a pitch raise to begin with of roughly 50 cents. (Bass around 30 cents, lowest tenor around 70 cents, tenor 40-50 cents, mid treble about 30 cents below the treble / tenor break, 50 above tapering off to around 70 in the highest treble) I saw a definant rise of 3-4 cents in the range C5 to F6 (which was what I looked at in my before and after testing). Now I dont know exactly what to make of this, but I thought I would throw it out there for any commentary or explanations anyone might have. Cheers RicB -- Richard Brekne RPT, N.P.T.F.
