One can use their voice to influence matter by using certain frequencies and tones to alter vibes and to create physical effects. Sound healing has been used for centuries to create balance and harmony, as it is believed to have the power to shift energy. One example is the didgeridoo, an Australian Aboriginal wind instrument that is believed to have healing properties when played. By using specific sounds and pitches, one can alter the energy and vibration of an object or space. Additionally, intonation and inflection can be used to create a sense of understanding or connection with an audience.
