style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I had a question from my
apprentice that someone on the list may be able to help me with. We all know
that vibrating strings divide up into segments with lengths approximately
equal to fractional portions, i.e. ½, 1/3, ¼, 1/5, 1/6, etc. (we’re not even
taking inharmonicity into account at this level.) His question is, “Why does
the string divide into all of the different available fractional segments and
not just even multiples of two?” I was hoping for a much better answer than
just, “Because it does” but Benade, Helmholtz and Rayleigh, the best I can
tell, all assume this to be a fact and I don’t really find the
“why.”<o:p></o:p></SPAN></FONT></P>
