The kyi zi [in Burmese ချည်ငင်
is a type of flat gong as used in Buddhist rituals in the temples in
Myanmar (Burma). Typically these gongs are suspended outside corner and
struck when a donation is made to the temple. When spinning the kyi zi
create a beautiful display of overtones combined with sound changes and
spin delay. These instruments come in a size of three inches to 20
inches across. Some web sites may name this instrument "gansadan" but
this is incorrect.
