Mock tuning test ??

[Brian Henselman]

I really appreciate finally learning these offsets.  However these are only
the "ideal".  When I took my test in 1992, it was just following an exam
just minutes before.  The previous exam had just failed and ran way over, so
the "detuning" for my exam was winged aurally.  I was expecting a methodical
detuning as listed below, however what I heard was quite a surprise.
Fortunately someone had given me the following really valuable advice in
coping with the exam.

His advice was, race through and rough tune the de-tuning back to normal
ASAP.  Then go back and retune for real.  This second pass will give you a
chance to hear a piano from a normal position, and won't be so
dis-orienting.  Navigating that de-tuning during the exam is the only hard
part of the exam.
