community and adjacent regions together, helping unify communities that otherwise may not have interacted with one another. Traditionally, when performers play kulintang music, their participation is voluntary. Musicians see performances as an opportunity to receive recognition, prestige and respect from the community and nothing more. kulintang music differs in many aspects from gamelan music, primarily in the way the latter constructs melodies within a framework of skeletal tones and prescribed time interval of entry for each instruments. The framework of kulintang music is more flexible and time intervals are nonexistent, allowing for such things as improvisations to be more prevalent. Angklung Angklung is a bamboo musical instrument native to Sundanese people of West Java. It is made out of bamboo tubes attached to a bamboo frame. The tubes are carved so that they have a distinctive resonant pitch when being vibrated. Each angklung only plays one note. This musical instrument made of bamboo is played by shaking it. The sound of the Angklung is generated from the impact of bamboo tubes. It has a distinctive sound that vibrates in a composition of 2, 3, to 4 notes in each size. Angklung existed before the Hindu era in Indonesia. In the days of the Sundanese kingdom (12th to 16th centuries), Angklung became a musical instrument that was always used in various events or celebrations, especially traditional events in farming. At that time, Angklung was played as worship of "Dewi Sri", namely the Goddess of Rice or the Goddess of Fertility to be given blessings to the plants she planted and also to prosper in life. Not only that, during the Sundanese kingdom, Angklung was also used as a trigger for the spirit of war. The types of bamboo that are commonly used as musical instruments are black bamboo (awi wulung) and ater bamboo (awi temen), which when dry are whitish yellow. Each note (barrel) is produced from the sound of the bamboo tube in the form of a blade (wilahan) for each bamboo segment from small to large. Each bamboo size has a different pitch. UNESCO designated the angklung a Masterpiece of the Oral and Intangible Heritage of Humanity on 18 November 2010. Suling Suling is the Sundanese word for seruling the word of Indonesian, which means 'flute'. Made from bamboo, Indonesian flutes are always end blown and vary in size.
