The music of Polynesia is a diverse set of musical traditions from islands within a large area of the central and southern Pacific Ocean, approximately a triangle with New Zealand, Hawaii and Easter Island forming its corners. Traditional Polynesian music is largely an inseparable part of a broader performance art form, incorporating dance and recital of oral traditions; most literature considers Polynesian music and dance together. Polynesian music expanded with colonial European contact and incorporated instruments and styles introduced through a process of acculturation that continues to the present day. Although the European tradition of hymn-singing brought by Christian missionaries was probably the most important influence, others are evident; Hawaii's influential (“slack key”) music incorporated the Spanish guitar introduced in the late 19th century, and later introduced the steel guitar to country music. Hip hop and R&B influences have created a contemporary Urban Pasifika music genre with a strong Polynesian identity and supported by the annual Pacific Music Awards in New Zealand. Christian music In the 1790s, Christian missionaries arrived in Polynesia for the first time. Hymns and other forms of Christian music were instituted, and native musical genres were driven underground and prohibited. Soon, traditional polyphonic singing was merged with Christian styles and church singing, and along with brass bands became an important part of Polynesian music culture across the Pacific. Popular music Popular music in Polynesia is a mixture of more traditional music made with indigenous instruments such as the nose flute in Tonga, and the distinctive wooden drums of the Rarotonga, and local artists creating music with contemporary instruments and rhythms, and also a blend of both. In the 1980s, Fijian stars like Laisa Vulakoro and Lagani Rabukawaqa became popular across the Pacific.
