The article mentions pitch inflation and it reminds me of something I learned about symphony orchestras. I dated an symphony oboe player for a few years. Oboes players play the note used to tune the orchestra before performances because the oboe has a penetrating sound and has very limited tuning capability (due to their construction) so other instruments are tuned to the oboe. She said that the string players often wanted a higher "brighter" pitch than the true pitch for middle C. She had to carry an electronic tuner (about the size of a smart phone) to verify her pitch and resolve disputes with the some of the string players.
