Post up the speaking length, cover diameter and the note number on the piano. We can look at the tension to see if it is getting up near critical levels. Quite a few of us on the list have spreadsheets in which we can drop the numbers to see what is going on.</DIV> <DIV><BR><SPAN class=393004412-23092006><FONT face=Arial color=#0000ff size=2>                Well quite a few.......... of you know some stuff about scaling.  I am really ignorant.   Will a scaling program also provide some information about "how to think" about scales, what and why they are, so that persons with no experience can understand something about the whole thing?   I'd like to know enough not to be stupid, but haven't a clue about how one goes to learning such things. If there are scaling programs which help along that way, I'd sure like to know about them.  thanks. les bartlett</FONT></SPAN></DIV></FONT><BR> <P><FONT size=2>--<BR>No virus found in this outgoing message.<BR>Checked by AVG Free Edition.<BR>Version: 7.1.405 / Virus Database: 268.12.8/455 - Release Date: 09/22/2006<BR></FONT></P></BLOCKQUOTE></BODY></HTML>
