<html> <body> Andrew, That, IMHO, is because of the idiots who want the piano tuned to A442 of higher. That way, they might not have to do a pitch raise!

Concert Instruments should be tuned  to A-441 to more easily address requests for pitch changes. ..." By concert instruments I would assume they mean B's or D's.  A lot of roving orchestras, bands and even occasionally, soloists require this on their contracts.  When asked about this they usually comment on it as a matter of self-defence against pianos that end up under A4=440hz during concert conditions. As Guy Nichols noted, concert conditions usually don't mirror tuning conditions.  One of my venues is now well trained.  The D is on stage where it will be with full concert lighting two hours before I am scheduled to arrive to tune and prep it.  That is the exception.  They have agreed to keep it a 441 and I think the only ones who get cross-eyed are vocalists.  Even then the hall is cooler than it will be when it is packed full of enthusiastic audience.  I haven't bothered to check pitch on the piano during intermissions like Guy did to document pitch-drop in the halls he serviced.  No-one has had any complaints or requests for me on the pianos I service. (With the exception of a D born defective and sold to one venue here with the strings out-of-reach of action adjustments.  The Steinway tech. had broken off some drop screws attempting to raise drop above 1/4" and failed to mention anything to the university.  That warranty saga continues still without any end in sight other than a gift of action shims!) Gave me pause when I first saw it too.  Makes sense to me after consideration.

Page 57 of the Steinway & Sons Technical Refernce Guide does mention A440, but that wasn't model specific. Yes, I do like references and footnotes ...
