It is called a Sound Bath because it feels like the sounds are washing over you.
Participants typically lie down on yoga mats (welcome to sit up), close their eyes and focus on their breath as wave after wave of sound washes over them. A sound practitioner facilitates using combinations of frequencies to prepare the nervous system to go into the parasympathetic nervous system state. This creates the environment for the body to go into its own natural healing often relieving stress, and reducing pain.
Instruments used may include, but are not limited to : quartz crystal bowls, himalayan bowls, gongs, drums, shakers, chimes, bells, tingshas, and voice to name a few.
