How does one know or learn what hammer to fit to what scale? Is there a simple way of working this out? Is there a book on this? Have you written on this on this forum or somewhere else, and if you have, please can you direct me to the thread?
The best method is not one that will be readily available to you. I’ve done numerous classes and seminars giving the kind of theoretical background information that helps in making these kinds of decisions. And I’m not the only one; others have sharing their knowledge on these subjects as well. But the venue is
The Piano Technicians Guild and the seminars and conventions are held in the U.S. and, occasionally, in Canada.
There are no books available that would be of much help in learning how to select appropriate hammers for any given piano. At least none that I know of.
I have written on the subject from time to time but I have no idea what the headings of the theads might be. I make no attempt to keep track of such things.
There has also been a fair amount written on this subject by the various participants on
pianotech. Many technicians face these problems and it is a subject that continues to be discussed from time to time on that list. It is a fairly active list and there are usually some experienced and knowledgeable technicians participating who are willing to share their experience and knowledge. You can sign up through the PTG website (
www.ptg.org).
Pianotech is open to technicians around the world—it is not necessary that you be a member of PTG.
