The nagaswarams are in the A=432 Hz universally resonant, healing tuning (or if you prefer traditional Indian terminology... in tune with "sadja" of C# at 136.1 Hz or the OM sound). This is the way most music was intuitively tuned to until the Nazi-Rockefeller consortium conspired to introduce A=440 Hz tuning as the world standard which makes us more prone to aggression, anti-social behavior and sickness by being out of resonance with the chakras... particularly the heart chakra, seat of compassion. Snake charmers know that the frequencies of sounds produced by their instruments can "calm" the snakes and make them non-aggressive. Humanity is finally waking up too; the 432 Hz musical revolution is on the way.
