Relaxing music can be used to help reduce stress and anxiety. Different frequencies of binaural beats and solfeggio frequencies can promote relaxation and positivity, increase concentration and alertness, and promote healing. Binaural beats in the alpha frequencies (8 to 13 Hz) are thought to encourage relaxation, promote positivity, and decrease anxiety. Muscle Relaxation (Theta/Delta) Frequency starts at 12 Hz, ramps down to 7.83 Hz and remains there until 12 mins, then ramps down to 3 Hz and remains there until 25 mins, then ramps up to 7.83 Hz and continues until the end of the track. It is tuned to 528 Hz to promote inner peace, healing and DNA repair. Solfeggio Frequencies can also promote relaxation and healing. For example, the 396 Hz Solfeggio Frequency helps those who struggle with feelings such as guilt, fear, and grief.
