Music of Indonesia, Vol. 4: Music of Nias & North Sumatra - Hoho, Gendang Karo, Gondang Toba

Batak music refers to the traditional and modern musical practices of the Batak peoples of North Sumatra, Indonesia, including Toba, Karo, Simalungun, Pakpak/Dairi, Angkola, and Mandailing communities. It features distinctive gong-and-drum ensembles for ceremonies and social dances (tortor), most famously the Toba gondang sabangunan (with taganing drums, gordang bass drum, ogung gongs, sarune shawm, and hesek timekeeper) and the Mandailing gordang sambilan (nine large tuned drums). A contrasting chamber-like setup, the gondang hasapi ensemble, centers a two-stringed lute (hasapi) with xylophone (garantung) and bamboo flute (sulim), producing lyrical, heterophonic textures. Alongside ritual music, Batak communities developed a powerful choral tradition under Christian influence, and since the mid-20th century a lively Batak pop repertoire emerged, blending traditional melodies and poetic forms with Western harmony and instrumentation.

Gondang is the ceremonial ensemble music of the Batak (especially Toba Batak) people of North Sumatra, Indonesia. The term can refer both to the ensemble itself and to individual pieces (repertoires) performed for social and ritual functions. Two principal ensemble types are recognized: Gondang Sabangunan, a powerful outdoor set dominated by a five-tuned drum battery (taganing), a large bass drum (gordang), a quartet of tuned gongs (ogung), a double-reed shawm (sarune bolon), and a timekeeping idiophone (hesek); and Gondang Hasapi, a more intimate string ensemble centered on the two-string hasapi lute, sulim bamboo flute, small gongs, and frame drums. The music interlocks with the tortor dance and with call-and-response interactions between musicians, dancers, and ceremonial leaders. Gondang is inseparable from Batak social philosophy (dalihan na tolu) and life-cycle events—weddings, funerals, clan gatherings, and thanksgiving rituals—where specific pieces are invoked to bless, honor, lament, or energize the community.
