[CAUT] Duplex

[RicB]

Hi Jim

You hit the nail on the head here IMHO.  The real problems surrounding 
the classic Steinway front duplex scale are the difficulties in 
maintaining it.  And I will be the first to admit it is a temperamental 
beast.  But not overly so me thinks.  In my view more the problems are 
overstated from the standpoint of actual maintainance needed.   
Overstated at least in the sense that many go so far as to outright 
condemn it.

Now that said.... The Steinway sound that this is so connected with is 
just one of the many kinds of piano sounds available.  Other front 
termination schemes have their own sets of pos/negs and their own impact 
on the end sound of an instrument.  And many of these are quite 
successful too in their own right and for their own reasons. 

I think the diversity is a good thing.  Rather then simply condemning a 
given solution and thereby closing off one whole sphere of piano sound I 
believe we should be able and willing to exercise the necessary 
maintainces  to enable it to function as best it can within its own 
paramemters. 

And of course.... anyone who wants to explore other avenues should be 
likewise appreciated for adding to that exact same diversity.

Cheers

    David Love asked if I thought a sharp profile at the capo bar, combined
    with the duplex, would increase the inharmonicity.  No, I would
    expect it
    to decrease it.  In a later post, Ric Brekne described exactly what
    I was
    talking about.  However, it's difficult to maintain a capo bar radius of
    less than 0.5 mm if there is much pressure against it.
