This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment As a general rule I am finding that small pianos require an entry of -.5 = on the DOB and as the pianos get bigger that number decreases. But you = can measure the stretch before you start by tuning a double octave = (after entering the FAC numbers and saving), and testing aurally to see = if it is where you want it. The SAT uses A4 as the fixed point so keep = that in mind when you choose your test double octave. I usually try and = test the double octave to not include any wound strings. If the double = octave is too wide, input a negative number on the DOB and change notes = (step up, step down) to implement the change. Test again. When you get = it where you want it go ahead and start tuning. When tuning with the = SAT I start in the tenor and go up (when tuning aurally, I start from = the temperament and go down). When I am done with the treble I usually = direct tune the bass as the machine sometimes has problems across the = break and I don't always agree with its choices for stretch in the bass. = Jim Coleman has made several contributions to the list regarding use of = the DOB. I recommend you search the archives and check them out. =20 David Love=20 ----- Original Message -----=20 From: Farrell=20 To: pianotech@ptg.org=20 Sent: October 21, 2001 11:11 AM Subject: Re: more on this temperament thing I would sure like to hear more on this topic. As a tuner still on a = steep learning curve, I wonder just what I should be doing with my = octaves, but I find that the SAT III is either right where I wish it to = be, or sometimes I do find that it seems to have calculated a tuning = with too much stretch, and I have to enter negative numbers in the DOB = to slow the beating down - occasionally quite a bit.

To my ear, I usually reduce the stretch (on = the SATIII via the DOB). On concert grands I seem to prefer it a bit = under 40. On smaller grands and uprights, in the mid 30's. Of course = the general scaling does make a difference. But generally I find the = standard setting on a SATIII over stretches. I am curious what other = people find.

Could = you give us some numbers so we can know what you mean by tempered = octaves? =20 For example, when I tune a Steinway D my C6 is stretched to 5.06, = C7 is 16.11, and C8 is 43.84. This is what I consider a conservative = tuning. What kind of numbers do you get? On any piano, just measure = your C6, 7, & 8 and tell us what model piano it is, and how it stretches = with your tempered octaves. That would be very informative.
