The historical setting
Gamelan is the traditional ensemble music of the Javanese, Sundanese, and Balinese peoples of Indonesia, made up predominantly of percussive instruments. The most common instruments used are metallophones (played with mallets) and a set of hand-drums called kendang, which keep the beat. The kemanak, a banana-shaped idiophone, and the gangsa, another metallophone, are also commonly used gamelan instruments on Bali. Other notable instruments include xylophones, bamboo flutes (similar to the Indian bansuri), a bowed string instrument called a rebab (somewhat similar to the gadulka of Bulgaria), and a zither-like instrument called a siter, used in Javanese gamelan. Additionally, vocalists may be featured, being referred to as sindhen for females or gerong for males.
Related traditions are also found elsewhere in Maritime Southeast Asia, including Gamelan melayu (Malay Gamelan), a distinct courtly tradition associated with the Johor–Riau cultural sphere that has been documented since at least the eighteenth century and remains practised principally in Malaysia.
History
The gamelan predates the Hindu-Buddhist culture that dominated Indonesia in its earliest records and thus represents an indigenous art form of Indonesia. In contrast to the heavy Indian influence in other art forms, the only obvious Indian influence in gamelan music is in the Javanese, Sundanese, and Balinese style of singing, and in the themes of the Wayang kulit and Wayang Golek (shadow puppet plays). In Javanese mythology, the gamelan was created by Sang Hyang Guru in Saka era 167 (c. AD 230), the god who ruled as king of all Java from a palace on the Maendra mountain in Medang Kamulan (now Mount Lawu). He needed a signal to summon the gods and thus invented the gong.
For more complex messages, he invented two other gongs, thus forming the original gamelan set. The earliest image of a musical ensemble is found on the bas-relief of the 8th century Buddhist monument of Borobudur, Central Java. The Borobudur's musicians play lute-like stringed instruments, various kendang drums, various suling flutes, cymbals, bells, metallophones, and xylophones. Some of these musical instruments are indeed included in a complete gamelan orchestra. Musical instruments such as metallophones (saron, kenong, kecer), xylophones (gambang), the bamboo flute (suling), drums in various sizes (kendang), cymbals, bell (genta), and bowed and plucked string instruments were identified in this image.
Typical Javanese gamelan instruments
In the courts of Java, Javanese gamelan is grouped into 2 groups of gamelan, namely gamelan Pakurmatan and gamelan Ageng. Gamelan pakurmatan is the gamelan used for special Javanese court events and all of them are sacred gamelan. The gamelan pakurmatan consists of the gamelan kodhok ngorek, the gamelan monggang, the gamelan sekati, and the gamelan carabalen. As for the gamelan ageng is considered the most complete in the Javanese court. The Gamelan Ageng instruments are usually owned by the general public (artists, schools, studios, and other communities) in Java and outside Java. This gamelan is used to accompany arts or rituals either in the palace or in the general public, the gamelan can use a complete gamelan or less.
In Bali, the Gamelan instruments are all kept together in a balé, a large open space with a roof over the top of it and several open sides. Gambelan (the Balinese term) are owned by a banjar, nobility or temples and kept in their respective compounds. In case of banjar ownership the instruments are all kept there together because people believe that all the instruments belong to the community as a whole and that no one person has ownership over an instrument.
Religious rituals
Under the influence of the Hindu-Buddhist Majapahit kingdom, gamelan was used as accompaniment in religious ceremonies with tembang (singing) and wayang performances. Even an accompaniment to a king's performance. In the Negarakertagama manuscripts written by Mpu Prapanca in the 14th century. It is said that the gamelan accompaniment was used by King Hayam Wuruk in performing a mask dance with eight young people accompanied by a song from the Queen Mother. With the collapse of the Majapahit kingdom and being replaced by the Islamic kingdom of Demak led by Raden Patah, gamelan as a traditional musical instrument did not just disappear. Its function is used as a media tool for preaching Islam.
Gamelan's role in rituals is so important that there is a Javanese saying, "It is not official until the gong is hung". Some performances are associated with royalty, such as visits by the sultan of Yogyakarta. Certain gamelans are associated with specific rituals, such as the Gamelan Sekaten, which is used in the celebration of Mawlid an-Nabi (Muhammad's birthday). In Bali, almost all religious rituals include gamelan performance. Gamelan is also used in the ceremonies of the Catholic church in Indonesia.
