Subj: [kl] Reed strength
Date: Thu, 26 Nov 1998 22:15:32 -0500

OK - lets see if I got that right:

I noted that Mason (or Rigotti Co.) has stated that all reeds (for a given
instrument and by the same manufacturer) were cut to the same physical
shape, and that therefore the differences in strength were due to properties
of the cane used and not the thickness. There seems to be general agreement
on this, although there are differences in how folks think the strength is
measured, with Blumberg asserting that the marks on the reed but are the
measurement itself (sort of a Rockwell hardness test for reeds?) and (if I
read you right) Hausmann and Galper having other opinions. (BTW, I can't
find the marks in question on my V12's or ML Premiums - maybe I'm not
looking in the right place.)

Regardless of the method of measuring the final reed strength, if it is true
that the difference between a #2 and a #5 is all cane density, then several
conclusions follow.

1) A #2 reed out of the box is of less dense cane than a #5 reed shaved
down to play as a #2. This might have profound effects on reed life, tone,
etc. (This is an extreme example, but I, at least, often "soften" a reed by
1/4 to 1/2 grade with reed rush.)

2) If this is true, then persons who make their own reeds with mechinical
shapers should encounter the same wide range of inconsistency as the
manufacturers do. Comments from these persons?

3) The only reed measuring machine I know of (never seen one in the flesh)
is the "Reed-O-Meter" which, from the picture in the catalog looks as if it
is bending the reed and measuring the relative force required to make a
given bend, or the relative bend for a constant force (can't tell which).
This would be a direct measure of stiffness (whether useful or not) and not
density. If density is the key, it is a well-kept secret.

So I'm full of questions tonight, but without many answers.
