The Kenyah people are an indigenous, Austronesian-speaking people of Borneo, living in interior North and East Kalimantan, Indonesia and Sarawak, Malaysia. The Kenyah people, traditionally being swidden agriculturalists and living in longhouses (uma dado'''), is an umbrella term for over 40 sub-groups that mostly share common migration histories, customs, and related dialects. Kenyah people lived in longhouses a small communities. Each longhouse consists of families who choose their own leader (headman). When they have an event or celebration such as harvest festival, they will normally use the longhouse verandah (oseh bi'o) to gather and deliver speeches to guide their youngsters. Normally this harvest festival celebration (tau bio Ramay o o Ajau, pelepek uman) is a major festival because most of them are still farmers. Kenyah people are very creative. They compose their popular songs and melody such as Lan e Tuyang, Kendau bimbin, Ilu Kenyah Kua Lo Te'a, Pabat Pibui, Atek Lan, and Leleng Oyau Along Leleng. Popular traditional Kenyah musical instruments are such as jatung utang (wooden xylophone), sampe (a type of guitar), sampe bio (single-stringed bass), lutong (a four- to six-string bamboo tube zither) and keringut (nose flute). Christianity is the predominant religion of Kenyah people, with the majority belonging to the Evangelical Protestanism. Before the arrival of Christian missionaries, the Kenyah people practice a traditional form of animism called 'Adat Pu'un'. During the initial introduction of Christianity by Christian & Missionary Alliance and Borneo Evangelical Mission, traditional beliefs and practices were revitalized and this form was called 'Bungan Malan Peselong Luan' movement. Today, there are only a small number of Kenyah people who still practice the Bungan faith. It is believed that a person will ascend to Alo Malau (seven heavens) with their ancestors (tepun) after death. Statistical figures, based on the Indonesian and Malaysian national censuses collected in 2000, recorded a total of 44,350 Kenyah people in East Kalimantan, Indonesia and 24,906 in Sarawak, Malaysia.
