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 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, a bowed string instrument called a rebab, and a zither-like instrument called a siter, used in Javanese gamelan. Additionally, vocalists will be featured, being referred to as sindhen for females or gerong for males.
Gamelan gong kebyar is a style or genre of Balinese gamelan music of Indonesia. Kebyar means "to flare up or burst open", and refers to the explosive changes in tempo and dynamics characteristic of the style.

The Music of Java embraces a wide variety of styles, both traditional and contemporary, reflecting the diversity of the island and its lengthy history. Apart from traditional forms that maintain connections to musical styles many centuries old, there are also many unique styles and conventions which combine elements from many other regional influences, including those of neighbouring Asian cultures and European colonial forms.
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.
A kempul is a type of hanging gong used in Indonesian gamelan. The kempul is a set of pitched, hanging, knobbed gongs, often made of bronze, wood, and cords. Ranging from 19 cm to 25,4 cm in diameter, the kempul gong has a flat surface with a protruding knob at the center and is played by hitting the knob with the "soft end of a mallet." "The wooden mallet used has a ball shape head with heavy padding on a short wooden handle. The number of kempul gongs present in a gamelan ensemble varies but, "although there can be two to ten kempul on one separate rack, it is common to have five kempul hanging on the same rack as the Gong ageng and gong siyem".
Gamelan beleganjur is one of the most popular styles of gamelan music in Bali. Its closest Western analogue is probably the Western military band.
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.
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 puke 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.
The bonang is an Indonesian musical instrument used in the Javanese gamelan. It is a collection of small gongs placed horizontally onto strings in a wooden frame (rancak), either one or two rows wide. All of the kettles have a central boss, but around it the lower-pitched ones have a flattened head, while the higher ones have an arched one. Each is tuned to a specific pitch in the appropriate scale; thus there are different bonang for pelog and slendro. They are typically hit with padded sticks (tabuh). This is similar to the other cradled gongs in the gamelan, the kethuk, kempyang, and kenong. Bonang may be made of forged bronze, welded and cold-hammered iron, or a combination of metals. In addition to the gong-shaped form of kettles, economical bonang made of hammered iron or brass plates with raised bosses are often found in village gamelan, in Suriname-style gamelan, and in some American gamelan. In central Javanese gamelan there are three types of bonang used:
The kempyang and ketuk are two instruments in the gamelan ensemble of Indonesia, generally played by the same player, and sometimes played by the same player as the kenong. They are important beat-keepers in the colotomic structure of the gamelan. Depending on the structure, they play different, repeating patterns every gongan. Not all structures use the kempyang, but the kempyang is never played without the ketuk.
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.
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.
Imbal or imbalan is a technique used in Indonesian Javanese gamelan. It refers to a rapid alternation of a melodic line between instruments, in a way similar to hocket in medieval music or kotekan in Balinese gamelan. "A style of playing in which two identical or similar instruments play interlocking parts forming a single repetitive melodic pattern."
This imbal is a method of playing in which the nuclear theme is played by one of the nyaga's 'broken up' into half-values, what time another player beats alternately with the first, but in such a way that his tones, each of which comes between two of his colleague's, are always one step lower than the nuclear theme tone immediately preceding it. From practical considerations this imbal is, if possible, divided over two demungs; if only one such instrument is available, the two players sit facing each other. The player who beats the nuclear theme tones is said to play the gawé (...); the other one, the nginţil (...).
The merong is a section of a composition for Javanese gamelan, a musical ensemble featuring metallophones, xylophones, drums, and gongs. Specifically, the merong is the initial part of a gendhing. A merong cannot be played on its own, but must be followed by a minggah, which may also take the form of a ladrang or other colotomic structure.
The minggah or inggah is a section of a gendhing composition for gamelan.
A gatra is a unit of melody in Indonesian Javanese gamelan music, analogous to a measure in Western music. It is often considered the smallest unit of a gamelan composition.
A gong chime is a generic term for a set of small, high-pitched bossed pot gongs. The gongs are ordinarily placed in order of pitch, with the boss upward on cords held in a low wooden frame. The frames can be rectangular or circular, and may have one or two rows of gongs. They are played by one to four musicians, each using two padded sticks to strike them. They are an important instrument in many Southeast Asian musical ensembles, such as Indonesian gamelan, kulintang, or Thai pi phat. For this reason, such ensembles are sometimes called "gong chime ensembles" or "gong chime orchestras," and the broad variety of music "gong chime music."
