The effect of sound on the body, mind and psyche of living beings is manifold. Harmonic sound sequences can contribute to the welfare and health preservation. Additionally to various keynotes and overtones there are vibrations which act on the body to support the natural oscillations of the cells. These are physical phenomena that have nothing to do with esotericism.
Mental and physical tension can be degraded by a sound massage. Please note that it is not a therapeutical approach in the conventional medical environment. The use of sound equipment does not replace the visit to a therapist or doctor.
