I follow pretty much exactly what = you described in your post below when I tune. I usually test some sample = octaves all across the keyboard to get a feel for what I will be wanting to do with = the DOB. I have all of Jim Coleman's info and have studied it extensively. When I = said that I wonder what I should be doing with my octaves, I was referring to = the upper treble (as in your original post) and was indicating that I know = very little about upper treble stretch theory - why some tuners stretch more = than others, why some stretch a big piano on a stage more than a small piano = in a home. When techs are talking about these various amounts of = stretch, what are they doing with the amount of beating in octaves and double and = triple octaves way up in the high treble? Are we talking only about putting a = half or a quarter bpm in some type of octave, or lots of beats or what? Any = thoughts would be welcome.</DIV> <DIV> </DIV> <DIV>Terry Farrell</DIV> <DIV> <SPAN id=__#Ath#SignaturePos__></SPAN> </DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=davidlovepianos@earthlink.net href="mailto:davidlovepianos@earthlink.net">David Love</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Sunday, October 21, 2001 = 2:50 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: more on this = temperament thing</DIV> <DIV><BR></DIV> <DIV><FONT size=2>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.  </FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>David Love</FONT> </DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=mfarrel2@tampabay.rr.com href="mailto:mfarrel2@tampabay.rr.com">Farrell</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> October 21, 2001 11:11 = AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: more on this = temperament thing</DIV> <DIV><BR></DIV> <DIV>I would sure like to hear more on this topic.
