Canon, or tetsu-tsutsu

A set of bells on a stand consisting of high and low pitched bells with a hollow metallic piece in between of indefinite pitch. The 2 bells are usually tuned to a 3rd or 4th step, as in Latin music. The middle piece makes a metallic "ching" sound. The "canon" (or "tetsu-tsutsu" in Japanese) is used to play the basic beat.
