The Hmong still strongly maintain funeral rites, beliefs in souls, and the formal steps in the funeral rites. The musical instrument used in funerals is called “Keng”, a woodwind instrument with five keys made from materials available in the community. The structure of the music is divided into many parts without repetition. The components are complete with melody, chorus and rhythm. A player is free to raise or lower melodies by controlling his breathing, which is unique and special to funeral music. The Keng can be played with the Jua in funerals. During festivals, the Jang and the Yang are used in accompaniment with live singing. The Hmong believe that music is inseparable from funerals. Music and funeral rites are considered most important in their culture. It can be concluded that Hmong music is used to express feelings with chorus and improvised melodies. It is unique to the ethnic group.
