The music of Myanmar (or Burma) () shares many similarities with other musical styles in the region. Traditional music is melodic, having its own unique form of harmony, often composed with a (na-yi-se), a (wa-let-se) or a () time signature. In Burmese, music segments are combined into patterns, and then into verses, making it a multi-level hierarchical system. Various levels are manipulated to create a song. Harmony in Mahagita (the Burmese body of music) is known as twe-lone, which is similar to a chord in western music. For example, C is combined with F or G. Musical instruments include the brass se (which is like a triangle), hne (a kind of oboe), the bamboo wa, as well as the well-known saung, a boat-shaped harp. Traditionally, the instruments are classified into five groups called (). These instruments are played on a musical scale consisting of seven tones, each associated with an animal that is said to be the producer of the tone. Each tone can be raised, lowered, or played naturally (corresponding to sharp, flat or natural), resulting in twenty-one possible combinations. The pat waing drum circle, for example, consists of twenty-one drums, one tuned to each tone in each possible combination. Similarly, the Kyi Waing, a twenty-one gong instrument is struck with a knobbed stick placed alongside the pat waing. Western music gained popularity in Burma during the 1930s, despite the government's intervention. During the socialist era, musicians and artists were subject to censorship by the Press Scrutiny Board and Central Registration Board, as well as laws like the State Protection Law. Classical music was also introduced during the British occupation. Pop music emerged in the 1970s and was banned by state-run radio stations. However, many artists circumvented this censorship by producing albums in private studios and releasing them in music production shops. Rock music, called stereo in Burmese, has been a popular form of music since the 1980s. When the country's regulations on censorship were loosened in 2000, many pop groups emerged throughout Myanmar such as Electronic Machine, Playboy, ELF Myanmar, and the King. In August 2012, state censorship on music was officially abolished. Traditional music Classical traditions The orthodox Theravada Buddhism rejects music as being decadent, but despite this cultural backdrop, the Burmese monarchy along with the infusion of different regional music styles, created several classical traditions of Burmese music.
