Which part of tabla vibrates to produce sounds?

The part of the tabla that vibrates to produce sound is called the "puchi" or "siyahi." It is a small, black spot located near the center of the tabla head, made from a mixture of iron, clay, and flour. When the tabla is struck, the puchi vibrates and creates a distinctive high-pitched sound. The size and placement of the puchi affect the pitch and tone of the tabla's sound.
