Manipulation of musical frequencies to affect mood and emotional state has been around for centuries.
I'm surprised the movie 'Eyes Wide Shut' hasn't been mentioned, where there's reference to an occult ritual involving the repetitive playing of harmonic chords at a specific frequency.
Crowley made reference to harmonics in his Thelema teachings as does the Kabalah and Enochian Magic (Magick).
Once you get into concepts such as 'life force' and the universal ether, you can start to see how harmonious (and disharmonious) frequencies play a critical role in our existence.
Everything in the Universe and beyond is pure energy resonating at different frequencies. Electrical and electro-magnetic energy is bound on earth by the laws of physics, whereas in the Universe(s), they are bound by different laws which transcend even those offered by our limited understanding of quantum physics.
Utilization and Manipulation of ELF and VLF is at the center of the HAARP program, which deals with weather modification on the surface, and human behavioral modification more covertly.
When messing with your frequency manipulation software, just be careful not to hit 528hz, which is the 'Language of Light, 'Light' in this context meaning the Illuminated One, or Lucifer. You could end up invoking something with very low 'wife acceptance factor' which could leave behind a real mess on the living room carpet.
