This four-module online course is for anyone who wants to learn to overtone sing for meditation, healing, or simply the joy of it. Exercises and techniques will help you unlock their transformational qualities.
The ancient technique of overtone singing allows the simultaneous production of two or more notes by the same person. It makes audible the natural spectrum of the voice so that magical bell-like or flute-like sounds are heard above a single note or fundamental, creating a unique otherworldly sound.
Overtone Singing has its origins in Central Asia—Mongolia, Tuva and Tibet as well as in South Africa. This style of singing/chanting has been practiced for centuries in folk traditions and shamanic healing practices.
Experience the transformational qualities of this ancient practice through Ilka's music and guided meditations.
Allow you to enter into deep meditative states of alpha and theta, activating the body's autonomic nervous system and innate healing capacity.
Can be an effective relief from emotional stress and anxiety and help you access a profound sense of relaxation and calm.
Can bring the body's energy centers into balance and coherence through the effect of the harmonic ratios produced by the amplified overtones.

"I want to tell you that I have been addicted to your overtones for days now. It has taken me to really cool places, very quickly... While I did, my body was moving and feeling fantastic. I picked up my phone with my right hand, which I can't usually do."
