A gatra ("embryo" or "semantic unit" [1] ) 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 gatra consists of a sequence of four beats (keteg), which are filled with notes (or rests, pin) from the balungan . In general, the second and fourth beats of a gatra are stronger than the first and third, and the final note of a gatra, called the seleh , dominates the gatra. In other words, the gatras are like Western measures in reverse, with the strongest beat at the end. Important colotomic instruments, most notably the gong ageng , are played on that final beat. If the final beat in a gatra is a rest, the seleh is the last note played. It is not uncommon in gamelan repertoire to find entire gatras of rests. Note that the actual length of time it takes to play a gatra varies from less than a second to nearly a minute, depending on the tempo (laya) and the irama .
In kepatihan notation , gatras are generally grouped together in the notation of the balungan, with space added between them. There is, however, no pause between one gatra and the next. The different patterns of notes and rests in a gatra are explained at balungan .
Rahayu Supanggah considers the hierarchical nature of the four beats of a gatra to be reflected on a larger scale in gamelan compositions; in particular by the four nongan in a gongan of the merong and inggah of a gendhing . This is similar to the padang-ulihan ("question-answer") structure key to gamelan composition. [2]
At least two sets of terms are used to describe the four notes of a gatra:
Ki Sindusawarno's system: (1) ding kecil (2) dong kecil (3) ding besar (4) dong besar
Martopangrawit's system: (1) maju ('forward') (2) mundur ('back') (3) maju (4) seleh
The first word in the names is Ki Sindusawarno's system are similar to the names of the hierarchy of pitches used in Balinese music: ding represents the secondary note of a pathet , and dong is similar to the Western idea of tonic. Kecil and besar mean "small" and "large," respectively, so clearly this articulates the hierarchical system explained in the introduction, with the largest and most significant beat at the end of the gatra, and a somewhat smaller one halfway through.
The reference for the names in Martopangrawit's system is to kosokan, the direction of bowing of the rebab . It also reflects the idea that the second beat is stronger than the first and third, since drawing a bow tends to produce a stronger sound than pushing it. [2]
Although traditionally gatras have always contained four notes, a few recent experimental pieces have used gatras of other lengths, often because of Western music. An example by a Javanese composer is Pak Marto's Parisuka. [3]
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).
Pelog is one of the essential tuning systems used in gamelan instruments that has a heptatonic scale. The other, older, scale commonly used is called slendro. Pelog has seven notes, but many gamelan ensembles only have keys for five of the pitches. Even in ensembles that have all seven notes, many pieces only use a subset of five notes, sometimes the additional 4th tone is also used in a piece like western accidentals.
SlendroPlay (help·info) is one of the essential tuning systems used in gamelan instruments that have pentatonic scale. Based on Javanese mythology, the Slendro Gamelan tuning system is older than the pélog tuning system.
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".
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 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.
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."
The sèlèh note or nada seleh is an Indonesian music concept used in Javanese gamelan music. In Javanese gamelan music, the sèlèh note or nada seleh is the final note of a gatra, or four-beat melodic unit. As such it is the note which serves as the goal for all the various strands of the musical texture.
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.
Irama is the term used for tempo in Indonesian gamelan in Java and Bali. It can be used with elaborating instruments. It is a concept used in Javanese gamelan music, describing melodic tempo and relationships in density between the balungan, elaborating instruments, and gong structure. It is distinct from tempo, as each Irama can be played in different tempi. Irama thus combines "the rate of temporal flow and temporal density"; and the temporal density is the primary factor.
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 (...).
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.
The bedhaya is a sacred, ritualised Javanese dance of Java, Indonesia, associated with the royal palaces of Yogyakarta and Surakarta. Along with the srimpi, the bedhaya epitomized the elegant character of the royal court and became an important symbol of the ruler's power.
(Joseph) Vincent McDermott was a classically trained American composer and ethnomusicologist. His works show particular influence from the musics of South and Southeast Asia, particularly the gamelan music of Java. He was among the second generation of American composers to create and promote new compositions for gamelan.
