Pena is a mono string instrument falling in the lute category, slightly similar to some of the traditional Indian stringed musical instruments such as the ravanahatha, ubo or the kenda. It is the traditional musical instrument of Manipur, used mainly in the Lai Haraoba festival of Sanamahism. Pena playing is becoming a dying art as only 145 active Pena players are reported in Manipur. The Center for Research on Traditional and Indigenous Art (Laihui), an organization headed by renowned pena player, Khangembam Mangi Singh has mandated vision to revive pena music.
