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.
They are shaped like bonang, but are generally placed in their own frame (rancak). The kempyang is pitched higher (about one octave, although it depends if they are in the pelog or slendro set. Both have a central boss like the bonang, but the kempyang has a rounder top (like the higher bonangs), while the ketuk has a flat top (like the lower bonangs).
In the common numerical notation, kempyang strokes are marked by "-" while the ketuk is marked by "+". The ketuk pattern is used to classify longer gendhing types, where it refers to the number of ketuk strokes in a nongan.
A gong is a percussion instrument originating in East Asia and Southeast Asia. Gongs are a flat, circular metal disc that is typically struck with a mallet. They can be small or large in size, and tuned or untuned.
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/Kendang, which register the beat. The kemanak and gangsa are commonly used gamelan instruments in Bali. Other instruments include xylophones, bamboo flutes, a bowed instrument called a rebab, a zither-like instrument siter and vocalists named sindhen (Female) or gerong (Male).
Gamelan degung is a form of 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 among communities in other countries interested in Indonesia and gamelan music.
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. It is the most popular form of gamelan in Bali, and its best known musical export.
Gamelan surakarta A typical large, double gamelan in contemporary solo (Surakarta) will include, in the sléndro set, one saron panerus, two saron barung, one or two saron demung, one gendér panerus, one gender barung, one slenthem, one bonang panerus and one bonang barung, one gambang kayu, one siter or celempung, one rebab, one suling, one pair of kethuk and kempyang, one set of three to five kenong, one set of three to five kempul, one to three gong suwukan, and one gong ageng.
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.
Jaipongan, also known as Jaipong, is a popular traditional dance of Sundanese people from Indonesia. The dance was created by Gugum Gumbira, based on traditional Sundanese Ketuk Tilu music and Pencak Silat movements.
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.
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 Kenong is a musical instrument of Indonesia used in the gamelan. It is a kind of gong and is placed on its side. It has the same length and width. Thus, it is similar to the bonang, kempyang, and ketuk, which are also cradled gongs. Kenongs are generally much larger than the aforementioned instruments. However, the kenong has a considerably higher pitch. Its sound stands out because of its unique timbre. The kenong sticks are taller than that of the bonang. The kenong is sometimes played by the same player as the kempyang and 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.
The siter and celempung are plucked string instruments used in Javanese gamelan. They are related to the kacapi used in Sundanese gamelan.
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 Gamelan Sekaten is a ceremonial gamelan from central Java, Indonesia, played during the annual Sekaten festival. The word "sekaten" itself is derived from syahadatain or shahada, the first requirement for converting into Islamic faith. Traditionally it is played once per year, on the occasion of Mawlid, Muhammad's birthday, for the week from the 6-12 of the month of Mulud. On this celebration it is brought from the palace at 11 pm to two pavilions before the Great Mosque. It is played every day during that week except the Thursday night/Friday morning. On the eve of the birthday proper, it is returned at 11 pm.
