Just for the Info Re: Key size.
Well, I've just measured my 6-foot Concert Grand Piano (Kawai RX2), and 88 keys = 48 and a Quarter Inches. 5 octaves (C-C of course) is 33 and 3 quarter inches. Each White key measures 23MM (milimetres) across!
1 Octave (c-c) = 7 and 3 eighths' Inches
The Yamaha Pro 9000 - when I had it, was noticably smaller than a "proper" piano sized keyboard!
