136.10 Hz OM 3 (Mid OM / Heart Chakra) Tuning Fork - Unweighted
$53.99
Explore the central resonance of the OM frequency series with a clear 136.10 Hz tone for meditation, heart-centered reflection, and focused sound practice.
The 136.10 Hz OM 3 (Mid OM / Heart Chakra) Tuning Fork Unweighted is the third frequency in a six-level OM tuning fork system. Tuned to 136.10 Hz, this unweighted tuning fork produces a rich, resonant tone that can be incorporated into meditation, sound healing, chakra-focused practices, spiritual reflection, and intentional listening.
Known as OM 3 or Mid OM, this frequency sits at the center of the OM series, following 34.03 Hz OM 1 (Bone OM) and 68.05 Hz OM 2 (Low OM) and preceding 272.2 Hz OM 4 (High OM). Within chakra-based sound healing traditions, OM 3 can be incorporated into practices focused on the Heart Chakra, traditionally associated with compassion, connection, balance, and emotional openness.
The Heart Chakra association belongs to traditional and contemporary energetic practices rather than scientifically established effects of 136.10 Hz. The unweighted design makes this fork particularly versatile for non-contact sound work, meditation, and use around the body or within a practice space.

For Heart Chakra-focused practices, use the resonance as an auditory focal point during meditation directed toward the center of the chest, pairing the sound with intentions such as compassion, gratitude, connection, or emotional reflection.
OM 3 can be used independently or as part of the complete OM sequence. When working progressively, begin with OM 1 at 34.03 Hz, continue through OM 2 at 68.05 Hz, and then introduce OM 3 at 136.10 Hz, allowing each frequency to resonate naturally before moving forward.
