Why do some sound right with lots of stretch in the high >octave, and some need little at all. For example: I suspect that part of it is in the tuning of the aliquots (if it has any). Take a piano that you feel needs a big stretch, measure it, mute off ALL the non-speaking string segments and tune it again (aurally). You may find that without the sympathetic vibrations the piano will "want" to tune with less stretch. This may be why some tuners (<grin>) tune the last few notes quite sharp. Perhaps there is an extremely sharp partial in some of those segments which the tuner is attempting to match since their fundamentals die so quickly. If you find a grand where you think the high notes are too sharp, pluck down the aliquot segments to see if there are any that match them. Could that be the answer Frank's looking for?
