Simple physics: the strings are not uniform along their lengths,
something that is actually difficult to achieve but something we have
become accustomed to with newer more sophisticated methods of making
strings.

Dear Collective wisdom,
I have been tuning my 5 and 6th course in octaves for years, with
wound
strings and gut or nylgut.
recently I bought the CD loaded strings from Mimmo and am slowly
getting used to them. I have thus replaced the fundamental with CD
loaded, while keeping my octave strings in gut or nylgut, this on two
different lutes.
I have noticed that the octaves are horribly out of tune as I go up
the
neck, especially by the time you get to the 7th fret. I realize I
rarely have to play up there, but it bothers me. Am trying to
figure
out what the problem is.. would it be a mismatch of tension? or would
it be the Loaded CD strings, that as some of you have probably found
to
be very elastic. I have never had this issue with wound string/gut
combinations.
I will be testing each string individually to check which one goes
out
of tune as you move up the scale, but I suspect it is the Loaded
string
that is giving me the problem.
any comments?
Bruno
