Indonesia's colorful and richly diverse culture is the result of the country's 17,508 islands and 34 provinces. The Indonesian archipelago has a treasure trove of many authentic dances and instruments. Angklung is one of the traditional musical instruments typical for the area. It is made of bamboo stems. On November 16, 2010, UNESCO officially recognized the Indonesian angklung as a Masterpiece of the Oral and Intangible Heritage of Humanity. The angklung is made of a varying number of bamboo tubes attached to a bamboo frame. The tubes are carved to have a resonant pitch when struck and are tuned to octaves. The angklung is popular throughout the world, but it originated in what is now West Java and Banten provinces in Indonesia, and has been played by the Sundanese for many centuries. The word angklung may have originated from Sundanese "angkleung-angkleungan", suggesting the movement of the angklung player and the "klung" sound that comes from the instrument. You can see how the performers from Jakarta, Indonesia, who won the Grand Prix "Golden Orpheus" at the XI Black Sea Festival "Euro Folk" 2014, play the traditional musical "treasure".
