It's good to Hmong instruments being sold online with respect and credit given to the skilled makers who keep traditional crafts alive. Chong Moua Lee is also featured on the Washington State Arts Commision website in an article about music at the Hmong New Year festival.
From the article:
People also play other insturments at New year as a form of courthsip; the raj, a single bamboo pipe with a reed and the ncas, a tiny bamboo [brass] jew’s harp. Chong Moua Lee learned to play both instruments when he was young. “Youth in the Hmong people, they’re really shy. When they’re falling in love, they’re not going to tell anybody. So they will blow it to give the missing part of your heart. Boys always go at night to talk to girls, and they will use the ncas to communicate through the wall. And it’s not to say in the real words, but to speak in the ncas, so the girls and the boys, they get to know each other and fall in love.”Lots more articles about Hmong music and culture from the WSAC.
