Our Body-Mind-Spirit is connected to Music. This is proven scientifically. The frequencies are encoded deep in our sub-conscious mind and they reflect in our spirit. This is why Pregnant mothers are asked to hear some melody and soothing songs when the baby is inside the womb.
There is lots of connection between Music and our soul. The Musical frequencies can transform particular energies from one part of body to another. The reason is, when we listen to Music, there are electrical movements in the brain. We can measure the movements with an instrument called an electroencephalograph (EEG).
This picks up the frequency of brain waves through electrodes placed on the scalp. The frequencies are called as beta, alpha, theta, and delta waves. Beta waves are active. This happens when we are most alert.
Alpha waves are slower. Alpha waves support tri-level consciousness and receptivity to energy enhancing activities. Theta are even slower than alpha. They are fondly called as Dreamer's brain. Delta waves are the lowest frequency. This is the state of mind in which deep, dreamless sleep occurs. It is the frequency associated with trances.
