Hi All,  This is a copy of the letter I sent to Encyclopedia Britannia
concerning their latest information about player pianos.

> Dear Sirs,
> 
> The following paragraph was sent to me by L. Douglas Henderson in
> response to his inquiries about 'player pianos'.
> 
> "By the 1990s the Yamaha Corporation, a Japanese piano manufacturer,
> had introduced the "Disklavier," a player piano that, by storing data
> on a computer disk, could re-create virtually every nuance of a
> performance--the tone, touch, timing, and dynamic range of a real
> performance."
> 
> If you are not already aware, it is 100% impossible for _any_ player
> mechanism, pneumatic or electronic, to change the "tone" of the music
> or the piano. The tone of a piano is established when the piano is
> made and it is different on every instrument.
> 
> Respectfully Submitted,
> John A. Tuttle
