The 8, 9 and 10" Classic Frosted Bowls are perfect when you are looking for an easily portable bowl or need to use one in a small space. You get a good note choice in these sizes too, as these sizes are often available in F (Heart), F# (Thymus), G (Throat), G# (Zeal at base of skull), A (Third eye) and B (Crown). The 11" or 12" usually provides tones in C (Root Chakra), D (2nd/Sacral) and E (Solar plexus).
The pitch of the Classic Frosted Bowl deepens as the size increases. Get an 18 or 20 inch singing bowl and you will think that Tibetan monks or humpback whales have moved in with you! These large bowls are especially powerful for taking outside and using in Earth healing ceremonies. Remember that this is quartz crystal and still has its innate resonance with the entire natural world.
