Kent, all this is fine and well, and it points out a need in the industry to produce a more standardized pitch source (if indeed that is really neccessary). But I fail to see how it should be neccessary to bring this issue into the examination process. I give the following reasons. 1. Considering the time and effort it takes to set up a tuning exam, and the cost to the examinee, it is ridiculous to fail said examinee simply because his tuning fork is out of tolerance. If fork accuracy is such a big deal, it is easy enough to check its accuracy before setting up tests. 2. I can not see that the ability to manufacture or remanufacture a tuning fork has anything directly to do with the skills neccessary to tune a piano. This requirement in essence is out of scope. 3. There is a built in paradox to the testing procedure regarding this point. It consists of the fact that "real" A440 must be achieved, yet one must achieve this aurally, not visually. The only possible point to insisting on the aural performance of this task is to prove the examinee can match the piano to the source with his ear. That in itself has nothing at all to do with what pitch the fork is at. The requirement that the fork be at real 440 is thereby isolated from the skill we are testing. If it was pitch accuracy that was paramount, then the requirement for aural achievement of this pitch would not be neccesary. My point is simply that this kind of thing has no buisness being a direct part of the testing proceedure. Rather, (if it is deemed neccessary) it should be a seperate pre-requisit for being allowed to take the tuning exam in the first place. On a par with the practical, and written parts of the exam. No one dissagrees with the need to provide accurate pitch sources. But it is not the tuners fault that his 80 dollar Primson Greely is two cents off because of temperature fluxuations. And if such errors are of earth shaking importance, then why not just allow for visual sources as well as anything else that gets the job done. ? Sounds too me like some change in the test got implemented cause folks got the feeling they needed to do something, anything, but something. Richard Brekne I.C.P.T.G. N.P.T.F.
