Philippe, A "dumb" string does not produce partials - or very little. Sounds like knocking your finger on wood. Such strings can be badly made or they can have too big mass for the specific speaking lenght. You might have seen it in some small grands from Grotrian and others where they have put in strings with 3 cupper wounds. They are not able to vibrate even if heavy hard hammers are used. The strings might even "die" simply of age. Another stringkiller is when a mouse has come into the piano and take a pee on the basstrings.

What does it means, when you say that a string goes "Dumb", or 'Dead" like Vince Mrykalo said ? What happens in terms of sound, and in terms of its inner structure ? How do you recognise it ?

It actually worked on a piano I tuned. Aras "William R. Monroe" <pianotech at a440piano.net> skrev: Hi folks, How about iron wound strings? I've a client with a rather old Baldwin that has iron wound strings, in need of a new pinblock/strings, etc. The client is interested in keeping the strings iron wound and I've never replaced irons wound with copper wound. Are there pitfalls to be aware of? What kind of tonal difference would one expect if we were comparing new iron to new copper? I'd also be interested in arguments in favor of and against keeping them iron. Many thanks, William R. Monroe --------------------------------- Stava rätt! Stava lätt! Yahoo!
