How would the high electric guitar notes of world class guitarists measure with an electronic tuner?

For example the high notes from the great solo of Comfortably Numb - Pink Floyd.


Or high notes from Still Got the Blues - Gary Moore or Carlos Santana etc.


An online sine wave generator can be also used for measuring frequency by comparison.


Acoustic levels must be low as pitch (perception of height of a frequency) depends also on intensity.


If the notes of Dave Guilmor are measured to be high, be careful not to quickly judge Dave or the electronic tuner.


Dave as all great musicians when playing is intonating according to what a human being's brain wants to hear (ear brain octaves etc).


And the electronic tuner?


The electronic tuner is based on engineering octaves (integer multipleas of a given frequency).


Ear brain octaves and engineering octaves are not the same thing. Why should they be?
