The koukin is a jaw harp that is played in both Yunnan China and
Vietnam. There are two types of koukin, one made from bamboo and the
other made from metal usually brass. The brass koukin have three to
four lamellaphone. In neighbouring Yunnan China the Naxi or "Yi
Hehe" people play a bamboo version of the koukin. Constructed from a
piece of bamboo carved with a single lamellaphone. The brass koukin
are quite melodic and they do have a surprisingly pleasant sound.
Technique: The koukin is held to the mouth with
the left hand. For playing the brass koukin the method is achieved
through an oscillation of the index finger, middle finger and the
thumb. The thumb mainly plays a sympathetic tone and sometimes it
changes through the melody.
