A gourd is a hollow, dried shell of a fruit in the Cucurbitaceae family of plants. Gourds can be used as a number of things, including bowls or bottles. Gourds are also used as resonating chambers[?] on certain musical instruments including some stringed instruments and drums. Instruments of this type are common in Africa, South Asia, and the Caribbean. Gourds are also used as a tool for sipping yerba mate by means of a bombilla, in Argentina, Paraguay and Brazil, where it is called "cuia" (kOOya).
