Explore our 8 inch frosted crystal singing bowls. The main notes in a 8 inch bowl are 4th octave F, F#, G, G#, A, A#, B and 5th octave C, C#, D and D#. In the 4th octave notes, such as the F or G, the bowls are thinner so are quite vibrant. 8 inch bowls in general can play quite loud, though they have less sustain than larger bowls. A benefit of these bowls is that they are lightweight and portable, and easy to store. You can even hold these bowls in the palm of your hand and play them.
