    Charles, Jim is just making reference to the instructions for the =
RPT test which states that now matter how the technician normally tunes, =
on the test they want you to tune pure 2/1 octaves on the very top part =
of the piano. They just want you to prove that you can do it, that's =
all.=20

  I'm a little confused by Jim's statement below, from his email on =
Aural
  Octaves:

  Does that mean the stretch suddenly ends at the last octave? Or are =
you
  just cautioning us not to stretch too much on the exam? Those look =
like
  2:1 octaves to me, so it seems like the stretch just ends at the last
  octave, and the tuning curve levels out.

  Also, Jim, I hope you'll post your comments on bass octave tuning.

  Thanks,
