Each bowl is accompanied by a wooden stick that is covered with suede. As you move the stick around the perimeter of the bowl it creates a harmonic tone that becomes stronger as you go around each time. The bowl quickly appears to be singing. You can work with more than one bowl at the same time. Crystal bowls have definite eye appeal.
Clear bowls are lighter, more expensive and play best when held in the hand.
The sound from the clear bowls is often interpreted as more intense and pure, and is preferred by some. The frosted bowls also emit a powerful, resonance. The larger bowls are much more reverberant, with the tone lingering longer, simply because of the size and amount of crystal. The size of the bowl does not necessarily determine its note. A particular size of bowl may be available in more than one note or tone.
