Thanks Lee,

...for your input on Bergman pianos. It is curious that a piano  of Chinese 
origin produced in Korea with Mr. Pramberger's stamp on it should have a 
Nordic accent (I'm thinking of Ingemar Bergman the film maker). I'd like to 
know more about this piano because I have seen the new Pramberger concert 
grand in Valley Forge and I am particularly interested in the duplex scale 
design.

I have noticed that most pianos of Chinese origin include a duplex scale, and 
there seems to be some awareness of how to incorporate this feature in scale 
design, but there seems to be a universal shortcoming in all of these 
instruments. And that is that the duplex scale is not in tune...that is, 
according to CFT Steinway's concept which I thoroughly endorse, and which has 
proven to be a significant factor in creating good piano tone.

I must add, objectively, that certain asian manufacturers have made 
statements to me and to various technicians I have spoken with that they 
deliberately mute or tune the duplex scales out of tune for acoustic reasons 
by choice. I find this hard to accept because none of these defenders of the 
abstruse duplex scales can produce any statistical studies to support their 
dissonant conclusions.

My interest would be to find a way to tune all of their duplex scales and 
thus enhance the tonal qualities of their pianos. Since you service them, 
perhaps we have a common interest. I would welcome any information about the 
duplex scales of the Bergmans that you can provide.
