You misunderstand my point.  It is, of course, the relatively low breaking 
stress of gut (compared to modern nylon, say) which requires lowering the top 
one or two courses on a theorbo.
   
  You also seem to be unable to comprehend the elementary laws of physics. 
Might I suggest you read the archives.

  Hi Matyn,  

  If you can find gut (or even nylgut) strings that will allow a  theorbo of 
90cm in A to be tuned without re-entrant tuning, please, let me know. I will be 
willing to try them!    Diameter also have to do with tone quality. Such an 
extremely thin string on that string lenth would sound very flimsy. If you use 
a thicker diamenter, the tension would be unbearable for the instrument.
  If you think that the reason for the re-entrant tuning of the theorbo is not 
conditioned by physical reasons but musical, I can tell you that you are on the 
wrong direction of thinking.

  Setting the top one or two courses of the theorbo an octave down has nothing 
whatsoever to do with the diameter of the string (as pointed out many times 
before - see archives).   It has to do with the string length,  the string 
material and the pitch. This leads to the breaking stress related to the pitch 
at which a string of a given material and length will break. 
   
  Thus for two strings of the same material and length, the pitch at which they 
will break is identical.  For example, a string of say 10mm  in diameter will, 
of course, require a much greater force to break than one of, say, 0.01mm but 
it has a much greater cross-sectional area and the Breaking Stress (ie Breaking 
Force/Cross-sectional area) is identical for the two strings.

  Dear Craig,

The re-entrant tuning on the theorbo has its origins on the physical 
nature of gut strings. The long string lengths of this instrument 
makes impossible to get gut thin enough to have the 2nd and 1st 
strings at "normal" pitch. This apparent drawback, used with 
intelligence on continuo playing can actually be of help. The problem 
is that the re-entrant tuning makes the instrument somehow less 
logical and [EMAIL PROTECTED] have to study its possibilities 
carefully to make good use of it.
I hope this helps,
Greetings,

Alfonso
