To make this melody instrument of the Limbu ethnic group three bamboo pipes each about 4cm thick are attached together side by side. Each is longer than the previous one (approximately 12, 15 and 18cm) like panpipes. Musicians can reproduce different bird songs when playing the Phaamuka and it is also used to convey secrets and other signals. Like most Nepali folk instruments, the Phaamuka is made by the musician himself. He also decorates it in his own individual style, with materials he finds in his local surroundings.

Some select thick-walled bamboo while others prefer thin-walled. The choice is often influence by a musicians liking for a particular birdsong and his wish to emulate his favourite birdsong
