Package includes Sonic Ohm Tuning Fork (1088.8 hz), Activator, and Instructional Booklet. The Sonic Ohm is an excellent sound tool to help balance the energetic fields or Chakras of the body and for space clearing. The Sonic Ohm has a pleasing crystalline clarity, and is the highest frequency in the Ohm Therapeutics™ system. This higher expression of Ohm is also an earth tone, with its balancing and grounding properties. Explore more advanced sound layering techniques by combining the Sonic with the smaller tuning fork (544.4 hz) from the High Ohm Octave Set to create the Sonic Ohm Octave.
