Tritone Devil's Interval, Rockefeller Tuning Standard
The "Tritone" or "Devil's Interval" was historically avoided in music for its dissonant and unsettling effects on the human brain. In the 20th century, the Rockefeller Foundation pushed to change the standard musical tuning from 432Hz to 440Hz, a move some believe was intended to create mass agitation. Disney's "Fantasia" was used as a prominent showcase for this new 440Hz tuning standard.
