More Scaling Questions

[Newton Hunt]

Why don't you pick a hard subject for discussion?

The purpose of rescaling a piano is to find the optimum compromise
between inharmonicity and tension with breaking % being used to
determine if there are any overages.  Hammer contact time is a measure
of tone; short time being bright and long times being mellower, being of
little use except as a point of interest..

There are guide lines available through use of some of the other
jprograms that help guide you through tension and inharmonicity.  Al
Sanderson jpublished a group of papers on this subject you might like to
get.

Since little can be done about the bridges without replacing or
renotching your only guide is tension and inharm.  Changing these to fit
with neightbors is the purpose.

Bass strings, on the other hand,  very often need rescaling sinply
because most bass scales are often way of the charts of tension and
inharm.  Getting these two factors under control can vastly improve the
quality of the bass.  After all, you can do in a few minutes what it
would have taken an old scale designer months of calculations to do.

The guidelines provided by Roberts are good ones.  Reading his papers
again can be helpful in answering your questions.

Hope this is helpful.
