T terbangan refers to a type of tambourine used primarily in Islamic devotional music throughout Southeast Asia, including Indonesia, Malaysia, Brunei, and Singapore. It is often utilized to accompany religious rituals such as the zikir.
The instrument's name is derived from the Arabic word robbana. While it is central to Indonesian musical traditions, similar instruments are also used by the Cham people of Cambodia and are related to the Rabana used by the Sinhalese people of Sri Lanka.
