Given the question: Information:  - The xylophone (from the Greek words "xylon", "wood" + "phn", "sound, voice", meaning "wooden sound") is a musical instrument in the percussion family that consists of wooden bars struck by mallets. Each bar is an idiophone tuned to a pitch of a musical scale, whether pentatonic or heptatonic in the case of many African and Asian instruments, diatonic in many western children's instruments, or chromatic for orchestral use.  - A metallophone is any musical instrument consisting of tuned metal bars which are struck to make sound, usually with a mallet.  - Tembang sunda, also called seni mamaos cianjuran, is a style of classical vocal music that originated in the Priangan highland of western Java. Unlike Sundanese gamelan music, tembang sunda was developed in the court of the regent Kabupaten Cianjur during the Dutch colonial period (mid-nineteenth century). The traditional vocal portion is sung free verse poetry, the instrumental accompaniment being performed on kacapi (zither), suling (bamboo flute) and sometimes, rebab (violin). A more modern, and metrical, form of lyrics exists that is called panambih.  - Java (Indonesian: Jawa; Javanese: ; Sundanese: ) is an island of Indonesia. With a population of over 141 million (the island itself) or 145 million (the administrative region) Census released in December 2015, Java is home to 56.7 percent of the Indonesian population and is the most populous island on Earth. The Indonesian capital city, Jakarta, is located on western Java. Much of Indonesian history took place on Java. It was the center of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally.  - Kacapi is a zither-like Sundanese musical instrument played as the main accompanying instrument in the Tembang Sunda or Mamaos Cianjuran, kacapi suling (tembang Sunda without vocal accompaniment) genre (called "kecapi seruling" in Indonesian), pantun stories recitation or an additional instrument in Gamelan Degung performance.  - Gamelan Degung is a Sundanese musical ensemble that uses a subset of modified gamelan instruments with a particular mode of pelog scale. The instruments are manufactured under local conditions in towns in West Java such as Bogor. Degung music is often played at public gatherings in West Java, such as at local elections, as well as many other events. There is international interest in degung as well amongst communities in other countries interested in Indonesia and gamelan music.  - Kacapi suling is a form of Sundanese music from West Java. It is essentially "tembang Sunda" minus vocals, and also at interludes between songs at a typical Tembang Sunda performance. The higher pitched kacapi rincik, the lower pitched kacapi indung and the suling flute are the instruments used for kacapi suling. Kacapi suling has instrumental pieces performed in two different scales; the first four in laras pelog convey a light mood, the last four, in laras sorog are more slow and grave. The change to laras sorog usually takes place at midnight and lasts til sunrise.  - The siter and celempung are plucked string instruments used in Javanese gamelan . They are related to the kacapi used in Sundanese gamelan . The siter and celempung each have between 11 and 13 pairs of strings , strung on each side , between a box resonator . Typically the strings on one side tuned to pélog and the other to slendro . The siter is generally about a foot long and fits in a box ( which it is set upon while played ) , while the celempung is about three feet long and sits on four legs , and is tuned one octave below the siter . They are used as one of the elaborating instruments ( panerusan ) , that play cengkok ( melodic patterns based on the balungan ) . Both the siter and celempung play at the same speed as the gambang ( which is rapidly ) . The name `` siter '' comes from the Dutch word `` citer '' , which corresponds to the English word `` zither '' . `` Celempung '' is related to the Sundanese musical form celempungan . The strings of the siter are played with the thumbnails , while the fingers are used to dampen the strings when the next one is hit , as is typical with instruments in the gamelan . The fingers of both hands are used for the damping , with the right hand below the strings and the left hand above them . Siters and celempung of various sizes are the characteristic instrument in Gamelan Siteran , although they are used in many other varieties of gamelan as well .  - Indonesia (or ; Indonesian: ), officially the Republic of Indonesia, is a unitary sovereign state and transcontinental country located mainly in Southeast Asia with some territories in Oceania. Situated between the Indian and Pacific oceans, it is the world's largest island country, with more than seventeen thousand islands. At , Indonesia is the world's 14th-largest country in terms of land area and world's 7th-largest country in terms of combined sea and land area. It has an estimated population of over 260 million people and is the world's fourth most populous country, the most populous Austronesian nation, as well as the most populous Muslim-majority country. The world's most populous island of Java contains more than half of the country's population.  - The rebab ("rabb", variously spelled "rebap", "rabab", "rebeb", "rababa" and "rabeba", also known as jawza or "joza" in Iraq) is a type of a bowed string instrument so named no later than the 8th century and spread via Islamic trading routes over much of North Africa, the Middle East, parts of Europe, and the Far East. The bowed variety often has a spike at the bottom to rest on the ground (see first image to the right), and is thus called a spike fiddle in certain areas, but plucked versions like the "kabuli rebab" (sometimes referred to as the "robab" or "rubab") also exist.   - Bali (Balinese: ) is an island and province of Indonesia. The province includes the island of Bali and a few smaller neighbouring islands, notably Nusa Penida, Nusa Lembongan, and Nusa Ceningan. It is located at the westernmost end of the Lesser Sunda Islands, between Java to the west and Lombok to the east. Its capital, Denpasar, is located in the southern part of the island.  - Gamelan is the traditional ensemble music of Java and Bali in Indonesia, made up predominantly of percussive instruments. The most common instruments used are metallophones played by mallets and a set of hand-played drums called "kendhang" which register the beat. Other instruments include xylophones, bamboo flutes, a bowed instrument called a "rebab", and even vocalists called "sindhen".  - Zither (or ) is a class of stringed instruments.
