<p><br>Isnt this a rather.... wide definition of a duplex Del ? I mean
when the get to the point of being 3-5 mm long and muted at that it seems
a bit of a stretch to call the thing a duplex.... or what ?
<p>--
<p><font face="Lucida Sans"><font color="#000080"><font size=+0>What would
you prefer to call it? Duplex simply means 'consisting of two parts.' Beyond
that we really have to get more specific. If we are going to go to the
trouble of tuning the duplex surely it's not too difficult to say so. And
we have a perfectly good word we can use: aliquot, meaning, "to divide
something exactly." Or we can say the duplex is "an aliquot part" of the
speaking length meaning the duplex is divided into some fractional part
of the speaking length.</font></font></font>

<p><br>Well, that may very well be the definition of the word duplex in
its most general sense, but in reference to pianos it more specifically
refers to the "duplex scale" and if one wants to really get picky one could
say it really refers to the definition as per Steinway. My point
is exactly the same point Ron made the other day. Over generalizing terms,
or using them this way or that just makes things muddy and leads to misunderstanding
what each other is talking about.
<p>Why not call these lengths what they really are in our context... in
the most general sense they are simply non speaking lengths. In more specific
sense they are front and back duplex lengths which may or may not be at
the same time an aliquot part. Correct me if I am wrong but doenst
the aliquot part infer whole number fractional parts... like 1/3, 1/4 etc...
not 0.25643 or the like ???
<p>Just in the interest of speaking the same language .....roughly
