5 Inch Copper Singing Bowl
Sometimes it's shocking how good the sound is coming from a small singing bowl. You might resonate with different keys. We have B, E, C, and G in these darker colored brass bowls.
In the West the heart chakra is F. The chakras look like this:
A: Third Eye
E: Solar Plexus
D: Seat of the Soul
C: Base of the Spine
Tibetans believe the heart is the key of D. That would make the Base Chakra: "A", and so forth.
