<HTML>Bill, Thanks for the suggestions.  I know that scaling is pretty math int= ensive.  I guess I'll have to ask my brother for a little help on under= standing some of this.  He's an advanced math instructor at a JC in Nev= ada, and the one who used up all the math genes for my entire family.

A properly drawn string scale is one whose attributes (tension, % of breaking point, inharmonicity, stiffness), when graphed, look like smooth curves. You'll find out quickly how achievable such smoothness is. Your difficulty with harmonizing the tenor section lies in the inharmoncity curve. For a wonderful introduction to that, you should start with Dan Levitan's series in the PTJ (starting I believe, in 9/73). As for calculating (and visualizing/graphing) an existing scale or a new one, buy "The Calculating Technician" by David Roberts (PTG Foundation Press), condensed from his series of 20 articles in the PTJ 1979-81. Once you've done that, you'll appreciate reading the original articles. </BLOCKQUOTE> </HTML>
