beating of drums
鼕 centers on the resonant beating of drums, specifically the deep, rolling sound they produce.
鼕 combines 鼓 (drum) with 冬, which likely contributes the sound トウ and may evoke the deep, resonant quality of winter or the booming of drums. The exact historical development is uncertain.
A drum 鼓 on top, and winter 冬 below. Imagine the deep, echoing beat of a drum rolling through the cold winter air.
For トウ, picture a toe tapping to the drumbeat: toe -> トウ, and the drum 鼕 keeps the rhythm.
