Irian Jaya's music has not been as well documented as Papua New Guinea's, partially due to the hostility from the Indonesian government towards the promotion of indigenous Melanesian culture.
By the beginning of the 20th century, Christian hymns, work songs and gold rush songs were popular, some in native languages and some in English or German. By the 1920s, recorded music had become popular and radio broadcasting of western popular music appeared by the late 1930s. A few years later, Allied soldiers and sailors during World War 2 popularized the guitar and ukulele while stationed in the Philippines and Hawaii. String bands became very popular by the early 1950s, and soon dominated the pop landscape. In the late 1960s, rock bands like the Kopikats had appeared in cities, while string bands like the Paramana Strangers had become well-known internationally. This was followed by the importation of bamboo bands, a style of music from the Solomon Islands using bamboo tubes played by hitting them with sandals. It first arrived in the area of Madang in the mid-1970s, and soon spread throughout the country.
After 1872, foreigners introduced Christian hymns, including Gregorian chanting. Peroveta anedia, ute and taibubu, all forms of Polynesian music, were also introduced in this period. The Gold Rush brought an influx of Australian miners who brought with them the mouth organ.
Traditional celebrations, which include song, dance, feasting and gift-giving, are called singsing. Vibrant and colorful costumes adorn the dancers, while a leader and a chorus sing a staggered approach to the same song, producing a fugue-like effect. 1933 saw television spreading across the country, and American popular music began having a major effect on Papuan music. Since 1953, singsings have become competitive in nature, with contests occurring in Port Moresby, Mt. Hagen and Goroka. 1949 saw the first Papuan to achieve international fame, Blasius To Una, begin his career.
By the end of the 70s, a local recording industry had appeared and artists like Sanguma and, later, George Telek, began mixing native and Western styles like rock and jazz.Pop music
Traditional music
Christian missionaries disapproved of Papuan folk music throughout the colonial period of the country's history. Even after independence, the outside world knew little of the diverse peoples' traditional music genres. The first commercial release to see an international audience didn't occur until 1991 (see 1991 in music), when Mickey Hart's Voices of the Rainforest was released.
