The music of Bhutan has traditional genres such as zhungdra and boedra. The influence of Drukpa Buddhism and Buddhist music on Bhutanese culture is important. Many folk songs and chanting styles are derived from Drukpa music. In the 17th century, during the reign of Zhabdrung Ngawang Namgyal (1594–1652) great blossoming of folk music and dance (cham) took place. Instruments dating to this time include the lingm (flute), dramnyen (lute) and chiwang(fiddle). ''Ynagchen'' is an instrument made from hollow wood with 72 strings that are "struck with two bamboo sticks." Rigsar music has become popular in Thimphu and Bhutan and is performed on electric piano and synthesiser. It is, however, a fusion of traditional Bhutanese and Tibetan tunes and is also influenced by Hindi music. The music albums are produced by many popular Bhutanese male and female singers not only in Rigsar music but also in traditional folk songs and religious songs. Four music CDs of religious folk music, called the 'Tibetan Buddhist Rites' released by the monasteries with a recording sung by a ''manip'' (a traveling ascetic) that reminisces the arrival of Zhabdrung Ngawang Namgyal in Bhutan in the 17th century is popular.
