Music is a great way of helping you to feel better and can be one of the most effective ways of pivoting from bad to good feelings. In the UK, apparently the sirens of the emergency services are set at the pitch most likely to create awareness, urgency, and even fear in the populace. In Nazi Germany, music and radios were set at the frequency most likely to create fear and certain types of consciousness in the populace. So there is mileage in the idea that pitch and frequency create feeling points and thought forms in people. 432Hz, must be the optimum frequency for creating certain positive vibrations within us, so let's all tune our CD players, radios, mobile phones and smart speakers to this. (And let's stear clear of propaganda).
This is very interesting. Nazis also first started adding fluoride to the water to keep prisoners docile and sedated.
