Archaic literary word describing the clear, resonant sound of bells, musical instruments, or stones being struck. Used in classical Japanese and Chinese-influenced writing.
The bell of the old temple resounds clearly.
In the poem, the ringing sound of jewels is depicted.
The exact derivation is uncertain; the kanji 鏗 and 鏘 both relate to metallic or stone sounds in classical Chinese, and the word was adopted into literary Japanese with the same meaning.
