Context: 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. , 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 minggah or inggah is a section of a gendhing composition for gamelan . It follows the merong , after an ompak . It is distinguished from the previous section by the use of kempyang . In the minggah section , the kempyang and kethuk play in the same pattern as in the ketawang , but with no kempul , and the kenong only where the gong ageng goes in the ketawang . Like the merong , it has a diversity of forms which can be specified by naming the number of kethuk strokes used . For example , consider `` gendhing kethuk 2 kerep minggah kethuk 4 . '' This means that in the minggah , there will be four gatras per nongan . The structure would then look like : pTp . pTp . pTp . pTpN pTp . pTp . pTp . pTpN pTp . pTp . pTp . pTpN pTp . pTp . pTp . pTpG where `` . '' indicates no interpunctuating instrument plays , p indicates the stroke of the kempyang , T the ketuk , N the kenong , and G the simultaneous stroke of the gong and kenong . Thus , in each section , the gong plays once , the kenong divides that into four parts , and then that is divided into parts according to the given structure . Here each nongan lasts 16 beats ( keteg ) , and thus the gongan lasts 64 . All minggah of this form are one gongan ( four nongan ) in length . However , the minggah may also use one of the other structures , especially the ladrang . If that is the case , the piece will be noted something like `` minggah ladrang '' . If the other section has a different title , that will be given as well ., 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"., Bali (Balinese: ) is an island and province of Indonesia.

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., 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., Subject: minggah, Relation: subclass_of, Options: (A) administrative region (B) area (C) capital (D) case (E) country (F) fiddle (G) fourth (H) greek (I) idiophone (J) image (K) island (L) javanese (M) majority (N) mallet (O) metallophone (P) music (Q) musical instrument (R) muslim (S) part (T) people (U) pitch (V) population (W) province (X) republic (Y) scale (Z) set ([) sound (\) sovereign state (]) spike (^) spread (_) string instrument (`) type (a) voice (b) wood (c) world (d) xylophone
