Khāēn
Legend holds that this free-reed instrument, played in the tribal music of Thailand and Laos, was invented to imitate the voice of the karaweik bird. To sound the Khāēn one exhales or inhales into a wind chamber to activate metal reeds which are attached to each bamboo pipe and concealed by the wooden chamber. Opening a finger hole above the chamber allows air to vibrate the reed and sound. Also found in Laos, this mouthorgan is related to others throughout Asia.
