Coleman vs Coleman Tuneoff

[Roger Jolly]

Hi Jim,
           A well written, thought provoking post. Loosen the standards on
temperament, but tighten the standards on false beat elimination and
voicing.  These two items mentioned, has a big effect on tuning, and
ultimately the musicality of the instrument.
Also some cause and effect test in the practical regulation part of the
test. As an expert tech, how many times have you cheated on a hammer line
to get after touch? 20mins  and the piano feels a lot better, vs a complete
regulation. 
Regards Roger
