In general, most people will be very happy with the pitch, and voice (quality of sound,) of a 10-14” Frosted Bowl, or 6-8” Handle Bowl. You can select a fairly wide range of pitches within this range of bowl types and sizes. These will fall in the range of an “A” below middle C, to a “G” above middle C. (Smaller hands will want only a 6” or 7” handle bowl, due to weight of the bowl, as you have to hold it. The Frosted Bowls sit on a table or floor surface, so this is not an issue with them.) Also, every pitch is never available in every size of bowl.
The Solid Handle Bowls are constructed with a solid quartz/glass handle. We find the 6”, or larger, Handle Bowls, consistently have the best resonant qualities. Most adults can easily play a 5, 6, or 7” Handle Bowl. The 8 and 9” bowls are heavier, and harder to hold for extended playing. We tend to recommend these only for larger, or more solid frame individuals, for this reason.
