The Karinding is Sundanese traditional musical instrument from West Java and Banten, Indonesia. It is usually made from bamboo and midribs of palm trees. Karindings made of palm tree midribs are traditionally used by male players, and bamboo instruments are used by female players.
Initially the karinding was used by ancestors to repel pests in rice fields, because the low decible sound from karinding can disrupt the insect hearing.
