Topic: Tritone

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.

Richard Merrick describes his discovery of the "devil in music," or the tritone interval, which the Roman Catholic Church banned for over 1,200 years. He explains how his university studies in Renaissance counterpoint revealed that strict musical rules were designed to avoid this specific interval. This historical suppression served as the catalyst for his development of harmonic interference theory and his investigation into how music was used for psychological control.
