[CAUT] Wire Stretch/ Stainless

[David Ilvedson]

Is there a sound recording of the wire in a modern piano?

No. It has a tendency to break (2%) more during restringing and requires a gentler handling. You can’t muscle it around the hitch pin to make the beckets point the same direction. This is also why Juan Mas Cabre meticulously buffs friction points. After stringing it seems the same as far as breakage goes. I only have 3 years experience with it, but it seems great so far.

List,



I'm no expert on wire but since I've used Pure Sound Wire I think I

should at least mention that this stainless wire is almost immediately

stable w/o any "prepping". I know it must be hard to believe... You

string a piano, chip it up to pitch, fine tune it, then place it in a

practice room and it acts like you did the stringing a year ago! Plus it

never rusts and has less inharmonicity. Only a slightly different sound.



I'm not sure what ramifications this has concerning "wire stretching"

etc. but I'll let you more scientifically minded techs tell me if it

does. Seems to be a BIG thing to me, but what do I know...



Regards,

Hi Ron,



Back in the bad old days when I was doing what Roger Jolly recommended

(i.e. seating strings with a small hammer and using a hammer shank as a

"drift") I never came across a string that went up in pitch. Some

strings

would not change pitch, and even in a single unison there were

differences

of zero to 35 cents among the three strings. I took a lot of

measurements

because I was hoping to create a "guesstimate" of how much to go beyond

A440, seat the strings, and end up near A440.



I think coils may squirm for many years. Certainly when I tighten them

stability is improved. Too bad we don't live longer--so we could see the

results of our (performed in good faith) actions 20 years later. Again

with

coils some strings seemingly don't change pitch even when they clearly

have

moved to tighter coils--and others may drop up to 150 cents.
