Final answer:
The buzzy sound of an mbira is created by the use of buzzing tines. When the tines are plucked or struck, they vibrate and produce a buzzing sound. This buzzing sound is a result of the tines being intentionally made loose, causing them to rattle against the resonating body of the instrument.
