Music Frequencies As Medicine
"The medicine of the future will be a medicine of frequencies!"
Quote from Albert Einstein
The 4.5 Hertz-Frequency is mainly used for trance-like states, as a heightened state of consciousness.
As a "medicine", the higher consciousness can provide the answer as to why you have a certain illness or why a certain part of your body is causing you pain. If you know the cause, you can first change it internally and transform it with another frequency, such as the 20 heart frequency offered here, to eliminate the pain.
