Hi, Ric, << I went to the site. He should document that. In other words state where he got that informantion and state where anyone else who wants to check on it can find it. I didn't see a reference to where he got that SnS used A457.2 fork. ---ric >> The single most comprehensive resource on the history of pitch is by physicist Alexander Ellis, "On the History of Musical Pitch," Journal of the Society of Arts 28 (1880): 293-336, 400-403. I understand that both the Steinway A-457 fork and the A-454 fork are documented there. Mendel has added his work to Ellis in "Studies in the History of Musical Pitch" (Amsterdam: Frits Knuf, 1968), so Ellis is currently available in this form at your local library. I understand the A-457 fork exists still, but am not sure where it is. I would like to know how important this pitch was for Steinway. As I speculated in an earlier post, certainly something must be in the Steinway Archives about this. Bill Shull, RPT
