Hi,Byron! Regarding Perfect Pitch and beats [not beets] recognition: I carry severall tuning forks,among them A-435,A-440,A-442 ,A-445 and a few altered A-440 and with those forks I was able to prove to severall clients,some Studio Musicians of high caliber,that all this is a myth.I,personally,do have ""pefect Pitch",can tell any note on any instrument in a different zip code,but it has nothing to do in our trade..All of us know that ,already. Try to play with different tuning forks,it's amazing listening experience!! Hope,this info helps..

I really question the concept of perfect pitch. Most people that claim that they or other family members have this trait are not accurate. What percentage of these people would be able to distinguish between two freshly tuned, similar pianos one at 440 and the other at 443. Especially if they would hear each after a period of time where they wouldn't have a fresh reference in their head.

Hello I am working on a Mason and Risch grand piano and the plate has a stamp that says " International Pitch A 435" . Is it best to tune this piano to A 435 ? The mother tells me the daughter has perfect pitch. She is away at school so I cannot talk to her. Would someone with perfect pitch be bothered by anything other than A 440? Jack Houweling Nobody has PERFECT pitch. Some people have very good pitch recognition. But to most of them, if you played A435 and asked them to tell you what note it was, they would just say "A," not "an A that's a bit flat." At any rate, the plate and frame can most likely handle having the pitch raised to 440. You might check to see that the plate bolts are snug. But yes, it was designed to be at 435. And 440 is only 5 beats per second sharp at A #49. There are probably times during humid summers when it's way sharper than that. --David Nereson, RPT -------------- next part -------------- An HTML attachment was scrubbed...
