(After all, the strongest partials = are those that will be heard most strongly by the listener. Duh!) TuneLab's inharmonicity measurements look at the full range of partials, but = only store the single calculated "inharmonicity constant" for the string. So when = I am preparing the tuning curve in TuneLab, I look at the mix of partial = strengths (viewable immediately after an inharmonicity measurement) and note the = strongest two or three partials. I do this several times for each = section of strings -- monochords, bass bichords, tenor bichords, and then again = for each set of trichords. In a Steinway I just tuned, the strongest partial = for the monochords was the 5th, and for the bichords it was the 4th. The 6th, = which is the default bass partial in Tunelab, was a quite weak partial in all = the bass, so I did not use it. I then change the partial selection to match the stringing p!<BR>attern and strongest partial in each section. Seems to = produce good results.<BR></DIV> <DIV><BR>---<BR>Outgoing mail is certified Virus Free.<BR>Checked by = AVG anti-virus system (<A = href="http://www.grisoft.com">http://www.grisoft.com</A>).<BR>Version: = 6.0.381 / Virus Database: 214 - Release Date: = 02/08/02</DIV></BLOCKQUOTE></BODY></HTML>
