The experiment is simple.
Music containing high notes from a great orchestra are played in the room at low volume (pitch perception depends on intensity).
A steady high note for example is matched to an online tone generator by inputing numbers until it sounds right to human brain perception.
Then the value in Hertz is compared to ordinary frequency, note tables. Or the note from the online generator is measured by an electron tuner. Or an electronic tuner directly listens to a steady high note from a great orchestra.
One is for a great surprise.
The electronic tuner will show all high notes to be substantially sharp.
There is nothing wrong with great orchestras nor with electronic tuners.
The difference is that great orchestras play for humans using human brain perception octaves whereas the electronic tuner measures engineering octaves which are exact integer multiples of a lower frequency.
This experiment can be repeated for various great electric guitar players bending by ear brain the high notes. For example Comfortably Numb - Pink Floyd electric guitar solo at the end.
