Sound baths are meant to help facilitate a shift in your brainwave state. Through frequency and entrainment with sound it's possible, and very easy, to down-shift our normal beta state (normal waking consciousness) to alpha (relaxed consciousness), with the majority of people able to reach theta (meditative state) and even delta (where internal healing can occur). This experience is helpful for anyone who wants to give themselves a moment of relaxation or gain the benefits from meditation, but has not yet learned how to access on their own.
For beginners, meditation requires a verbally guided experience, i.e- go to a quiet place and find a stream or repeat a mantra... The sound bath experience is about letting the sound take you to a deeper place making it easier to arrive in a relaxed state without complicating how to get there. Sound is the vessel and it allows you to explore and identify what a meditative state is and how it feels. Because of this, a sound bath is not only beneficial for beginners of meditation, a seasoned meditator will find as many benefits.
The sounds are created by a wide range of instruments with different frequencies which can include pulse drumming, Biosonic tuning forks, gongs, shruti box, Himalayan singing bowl, mbiru, various percussion, chimes, and overtone singing.
Sound baths are for groups of people where each person has their own personal space. The experience begins with each person lying down on a comfortable mat often with cushioning and an eye mask. After a few minutes of breath work the remainder of the experience is filled with different sounds and frequencies being introduced in succession. The purpose, and our collective goal, is to induce relaxation and explore personal inquiry.
