A month ago Cheryl informed me she was bored with the arrangement of furniture in our living room. Sadly I informed here the only place for her beloved Kawai NS-25 was beneath the "piano" window. Famous last words. At lunch today, I got up from the sofa (now located beneath the piano window) and checked the bass/tenor octaves. The lower notes are still a good 15 cents flatter then the upper, precisely where they ended up upon relocation of the piano. I wasn't sure what to do about this (aside from actually re-tuning that is), then I read Newton's reply, and now I have 10 great suggestions to take home! :>) Seriously though, I've put the "UST" question to Don Mannino. As for trouble shooting the "racking" problem, Bill Spurlock describes a little test (in his ad for a lid prop) where you lift up on the left corner of the cabinet while holding a bass/tenor octave. You will hear the beats change. You may want to access several models this way, before moving any around. An uneven floor will always be uneven, on which a four-legged (wheeled?) object will always wobble. However, a vertical piano with a good rigid case may not be as prone to conform to the dips and valleys. And of course, this is all just a semi-educated guess! Mark
