Fabien Maman developed the F Overtone scale tubes to ground the Root Chakra. Studies have shown that low F is the vibrational frequency of the circumference of the earth. With 15 sound tubes, the F Overtone Scale works to stretch the energy from the first chakra down to the earth, as it expands consciousness in the energy field. It is the perfect complement to the TEP Chakra Tubes®, grounding the client after they have been expanded and energized.
