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 by mallets and a set of hand-played drums called kendhang, which register the beat. The kemanak and gangsa are commonly used gamelan instruments in Java. Other instruments include xylophones, bamboo flutes, a bowed instrument called a rebab, siter, and vocalists named sindhen (Female) or gerong (Male).
Slendro is a pentatonic scale, Play (help·info) the older of the two most common scales (laras) used in Indonesian gamelan music, the other being pélog. In Javanese the term is said to derive either from "Sailendra", the name of the ruling family in the eighth and ninth centuries when Borobudur was built, or from its earlier being given by the god Sang Hyang Hendra.
The Music of Bali, Bali is an Indonesian island that shares in the gamelan and other Indonesian musical styles. Bali, however, has its own techniques and styles, including kecak, a form of singing that imitates the sound of monkeys. In addition, the island is home to several unique kinds of gamelan, including the gamelan jegog, gamelan gong gede, gamelan gambang, gamelan selunding and gamelan semar pegulingan, the cremation music angklung and the processional music bebonangan. Modern popular styles include gamelan gong kebyar, dance music which developed during the Dutch occupation and 1950's era joged bumbung, another popular dance style. In Balinese music you can also hear metallophones, gongs and xylophones.
A gamelan gadhon is an ensemble consisting of the 'soft' instruments of the Javanese gamelan. This can include rebab, gendér, gendér panerus, voice, slenthem, suling, siter, gong, kempul, kenong and kendhang.
A gendèr is a type of metallophone used in Balinese and Javanese gamelan music. It consists of 10 to 14 tuned metal bars suspended over a tuned resonator of bamboo or metal, which are tapped with a mallet made of wooden disks (Bali) or a padded wooden disk (Java). Each key is a note of a different pitch, often extending a little more than two octaves. There are five notes per octave, so in the seven-note pélog scale, some pitches are left out according to the pathet. Most gamelans include three gendèr, one for sléndro, one for pelog pathet nem and lima, and one for pelog pathet barang.
Mantle Hood was an American ethnomusicologist. Among other areas, he specialized in studying gamelan music from Indonesia. Hood pioneered, in the 1950s and 1960s, a new approach to the study of music, and the creation of the first American university program devoted to ethnomusicology, at the University of California, Los Angeles (UCLA). He was known for a suggestion, somewhat novel at the time, that his students learn to play the music they were studying.
The slenthem is an Indonesian metallophone which makes up part of a Javanese gamelan orchestra. The slenthem is part of the gendér family. It consists of a set of bronze keys comprising a single octave: there are six keys when playing the slendro scale and seven when playing the pelog. These keys are suspended by leather cords over individual bamboo tube resonators in a wooden frame, which are cut so that the placement of the bamboo's node causes the functional length of the resonator to be shorter for higher notes. The instrument is played by striking the keys with a mallet, called a tabuh, which has a short handle and a thin wooden disk edged in cloth or rubber. One hand is left free to dampen notes. It is a low-pitched instrument with a softer sound than the saron demung.
A gambang, properly called a gambang kayu is a xylophone-like instrument used among peoples of Indonesia in gamelan and kulintang, with wooden bars as opposed to the metallic ones of the more typical metallophones in a gamelan. A largely obsolete instrument, the gambang gangsa, is a similar instrument made with metal bars.
The saron is a musical instrument of Indonesia, which is used in the gamelan. It normally has seven bronze bars placed on top of a resonating frame (rancak). It is usually about 20 cm (8 in) high, and is played on the floor by a seated performer. In a pelog scale, the bars often read 1-2-3-5-6-7 across ; for slendro, the bars are 6-1-2-3-5-6-1; this can vary from gamelan to gamelan, or even among instruments in the same gamelan. Slendro instruments commonly have only six keys. It provides the core melody (balungan) in the gamelan orchestra.
The gong ageng is an Indonesian musical instrument used in the Javanese gamelan. It is the largest of the bronze gongs in the Javanese and Balinese gamelan orchestra and the only large gong that is called gong in Javanese. Unlike the more famous Chinese or Turkish tam-tams, Indonesian gongs have fixed, focused pitch, and are dissimilar to the familiar crash cymbal sound. It is circular, with a conical, tapering base of diameter smaller than gong face, with a protruding polished boss where it is struck by a padded mallet. Gongs with diameter as large as 135 centimeters have been created in the past, but gongs larger than about 80 centimeters are more common especially to suit the budget of educational institutions.
Kendang or Gendang is a two-headed drum used by people from the Indonesian Archipelago. Kendang is one of the primary instruments used in the Gamelan ensembles of Javanese, Sundanese, and Balinese, the Kendang ensemble as well as various Kulintang ensembles in Indonesia, Brunei, Malaysia, Singapore, and the Philippines. It is constructed in a variety of ways by different ethnic groups. It is a relation to the Indian mridangam double-headed drum.
Colotomy is an Indonesian description of the rhythmic and metric patterns of gamelan music. It refers to the use of specific instruments to mark off nested time intervals, or the process of dividing rhythmic time into such nested cycles. In the gamelan, this is usually done by gongs of various size: the kempyang, ketuk, kempul, kenong, gong suwukan, and gong ageng. The fast-playing instruments, kempyang and ketuk, keep a regular beat. The larger gongs group together these hits into larger groupings, playing once per each grouping. The largest gong, the gong ageng, represents the largest time cycle and generally indicates that that section will be repeated, or the piece will move on to a new section.
The balungan is sometimes called the "core melody" or, "skeletal melodic outline," of a Javanese gamelan composition. This corresponds to the view that gamelan music is heterophonic: the balungan is then the melody which is being elaborated. "An abstraction of the inner melody felt by musicians," the balungan is, "the part most frequently notated by Javanese musicians, and the only one likely to be used in performance."
Notation plays a relatively minor role in the oral traditions of Indonesian gamelan but, in Java and Bali, several systems of gamelan notation were devised beginning at the end of the 19th century, initially for archival purposes.
The panerusan instruments or elaborating instruments are one of the divisions of instruments used in Indonesian gamelan. Instead of the rhythmic structure provided by the colotomic instruments, and the core melody of the balungan instruments, the panerusan instruments play variations on the balungan. They are usually the most difficult instruments to learn in the gamelan, but provide the most opportunity for improvisation and creativity in the performer.
Pathet is an organizing concept in central Javanese gamelan music in Indonesia. It is a system of tonal hierarchies in which some notes are emphasized more than others. The word means '"to damp, or to restrain from" in Javanese. Pathet is "a limitation on the player's choice of variation, so that while in one pathet a certain note may be prominent, in another it must be avoided, or used only for special effect. Awareness of such limitations, and exploration of variation within them reflects a basic philosophical aim of gamelan music, and indeed all art in central Java, namely, the restraint and refinement of one's own behaviour." Javanese often give poetic explanations of pathet, such as "Pathet is the couch or bed of a melody." In essence, a pathet indicates which notes are stressed in the melody, especially at the end of phrases (seleh), as well as determines which elaborations are appropriate. In many cases, however, pieces are seen as in a mixture of pathets, and the reality is often more complicated than the generalizations indicated here, and depend on the particular composition and style.
Udan Mas is a composition for gamelan which is popular in Central Java, especially Yogyakarta. It is a bubaran, which is an ending piece played while the audience departs. In Western concert performances, it is often played as an encore. It is often one of the pieces students learn early in their studies.
Gamelan siteran is a casual style of gamelan in Java, Indonesia, featuring portable, inexpensive instruments instead of the heavy bronze metallophones of a typical gamelan. A typical group consists of varieties of siter, kendang (drum), and a large end-blown bamboo tube or a gong kemodhong, functioning as a gong ageng. A full group has a celempung, siter, siter panerus, siter slenthem, kendhang ciblon, and gong kemodhong. It is typically accompanied by singing as well. The instruments are often homemade, something which is impossible with the more characteristic gamelan instruments. Performances are usually of pieces from the standard Javanese gamelan repertoire.
Gamelan, although Indonesia is its origin place, is found outside of that country. There are forms of gamelan that have developed outside Indonesia, such as American gamelan and Malay Gamelan in Malaysia.
Gamelan Munggang are considered among the most ancient gamelans of the kraton (courts) of central Java. The ensemble of instruments consists of gong ageng, kempul, kendang and horizontal gong chimes tuned to three pitches. Very low in absolute pitch, each ensemble consists of two types: pelog and slendro. There is a repertory of several repetitive pieces, the best known permutation being high-middle-high-low. It is theorized that pelog was derived from the three note munggang scale. The origin of the munggang ensembles themselves are described in Javanese myths, however the first one may have been imported to Indonesia in the first century CE, with the first ensemble constructed by the Javanese made in the 4th century.
