Normally music is unfortunately tuned at 440 Hz. By using other tuning frequencies like for example 432 Hz, it is said that, one is in more contact with the scale of nature. There are actually several "magical" frequencies that appear when using the natural 432 Hz scale that is very beneficial for the human body. Pulse or BPM (Beat Per Minute) is also important in the equation.
Many listen to this music in their favorite mp3 Player when talking long walks or just doing some other relaxing activity. Headphones are recommended, specially for the TRT versions. It is a very nice complement listening to Chakra Massage Music when using the Shakti Acupressure mat.
