Besides the musical effect of the singing bowls and a China gong, pulsating sounds between the left and right side bowls create a vibrational pattern.

A balancing and harmonising effect between the left and right side of the brain occurs with these three wonderful pieces: "With a Quiet Mind," "Space - Planet-Suite" and "The Pleasure of Being One with the Supreme Soul."
