The bro is the tube zither of the Ede people of the Central Highlands of Vietnam. It is a quiet, intimate instrument well suited to its traditional use of accompanying love songs. It is made from a thin piece of bamboo with a gourd attached a third the length of the instrument from one end. There are two strings that extend the length of the tube, only one of which passes over three to five small frets held in place with wax or pitch. The bro is played in a similar manner to the Malagasy jejy vaotavo, and both probably share a common origin in the fretted stick zithers of India.
