A 
gamelan is a 
traditional musical ensemble from 
Indonesia, typically from the islands of 
Java and 
Bali, featuring a variety of 
instruments such as 
metallophones, 
xylophones, 
kendang (drums) and 
gongs; 
bamboo flutes, bowed and plucked 
strings. 
Vocalists may also be included. For most Indonesians, gamelan music is an integral part of Indonesian culture.
[1]
The term refers more to the set of instruments than to the players of  those instruments. A gamelan is a set of instruments as a distinct  entity, built and tuned to stay together – instruments from different  gamelan are generally not interchangeable.
Terminology
The word 
gamelan, referring only to the instruments, comes from the low Javanese word 
gamel, referring to a type of hammer like a blacksmith's hammer.
[2] The term 
karawitan refers to the playing of gamelan instruments, and comes from the word 
rawit, meaning 'intricate' or 'finely worked'.
[2] The word derives from the 
Javanese word of 
Sanskrit origin, 
rawit, which refers to the smooth, elegant sense idealised in Javanese music. Another word from this root, 
pangrawit,  means a person with that sense, and is used as an honorific when  discussing esteemed gamelan musicians. The high Javanese word for 
gamelan is 
gangsa, formed either from the words 
tembaga and 
rejasa (copper and tin) or 
tiga and 
sedasa (three and ten), referring to the materials used in bronze gamelan construction or their proportions.

 History of gamelan music

The gamelan predates the 
Hindu-Buddhist culture  that dominated Indonesia in its earliest records and instead represents  a native art form. The instruments developed into their current form  during the 
Majapahit Empire.
[4] In contrast to the heavy 
Indian influence in other art forms, the only obvious 
Indian influence in gamelan music is in the Javanese style of singing.
[5]
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.
[6]
The earliest image of a musical ensemble is found on the 8th century 
Borobudur  temple, Central Java. Musical instruments such as the bamboo flute,  bells, drums in various sizes, lute, and bowed and plucked string  instruments were identified in this image. However it lacks  metallophones and xylophones. Nevertheless, the image of this musical  ensemble is suggested to be the ancient form of the gamelan.
In the palaces of 
Java are the oldest known ensembles, the 
Munggang  and Kodokngorek gamelans, apparently from the 12th century. These  formed the basis of a "loud style". A different, "soft style" developed  out of the 
kemanak tradition and is related to the traditions of singing 
Javanese poetry, in a manner which is often believed to be similar to performance of modern 
bedhaya  dance. In the 17th century, these loud and soft styles mixed, and to a  large extent the variety of modern gamelan styles of Bali, Java, and  Sunda resulted from different ways of mixing these elements. Thus,  despite the seeming diversity of styles, many of the same theoretical  concepts, instruments, and techniques are shared between the styles.
[7]
 Varieties of gamelan ensembles

There is a variation of gamelan ensembles are distinguished by their  collection of instruments and use of voice, tunings, repertoire, style,  and cultural context. In general, no two gamelan ensembles are the same,  and those that arose in prestigious courts are often considered to have  their own style. Certain styles may also be shared by nearby ensembles,  leading to a regional style.
The varieties are generally grouped geographically, with the principal division between the styles favored by the 
Balinese, 
Javanese, and 
Sundanese  peoples. The Madurese also had their own style of gamelan, although it  is no longer in use, and the last orchestra is kept at the Sumenep  palace.
[8] Sundanese gamelan is often associated with 
Gamelan Degung, a Sundanese musical ensemble that utilises a subset of modified gamelan instruments with a particular mode of 
pelog scale. Balinese gamelan is often associated with the virtuosity and rapid changes of tempo and dynamics of 
Gamelan gong kebyar, its best-known style. Other popular Balinese styles include Gamelan and 
kecak,  also known as the "monkey chant." Javanese gamelan was largely  dominated by the courts of the 19th century central Javanese rulers,  each with its own style, but overall is known for a slower, more  meditative style than that of Bali. Although Javanese gamelan can be  made from steel, the better instruments are made of cast brass. The two  kinds of instruments are tuned in different ways.
Outside of the main core on 
Java and 
Bali,  gamelans have spread through migration and cultural interest, new  styles sometimes resulting as well. Malay gamelans are designed in ways  that are similar to the Javanese gamelan except they lack most of the  elaborating instruments and are tuned in a near-equidistant slendro,  often using a western Bb or C as a tuning basis. Javanese emigrants to  Suriname play gamelan in a style close to that found in Central Javanese  villages. Gamelan is also related to the 
Filipino kulintang ensemble. There is also a wide variety of gamelan in the West, including both traditional and experimental ensembles.
In oral Javanese culture distinctions are made between complete or  incomplete, archaic and modern, and large standard and small village  gamelan (On Concepts and Classifications of Musical Instruments,  Margaret Kartomi, 1990, U. of Chicago Press, p. 91). The various archaic  ensembles are distinguished by their unique combinations of instruments  and possession of obsolete instruments such as the bell-tree (
byong) in the 3-toned 
gamelan kodhok ngorek. Regionally variable village gamelan are often distinguished from standard gamelan (which have the 
rebab as the main melodic instrument) by their inclusion of a double-reed wind (
selompret, 
slompret, or 
sompret) in addition to variable drum and gong components, with some also including the shaken bamboo 
angklung or other instruments not usually associated with gamelan.
 Cultural context
In Indonesia, gamelan often accompanies dance, 
wayang  puppet performances, or rituals and ceremonies. Typically players in  the gamelan will be familiar with dance moves and poetry, while dancers  are able to play in the ensemble.
[9] In 
wayang, the 
dalang  (puppeteer) must have a thorough knowledge of gamelan, as he gives the  cues for the music. Gamelan can be performed by itself – in "klenengan"  style, or for radio broadcasts – but concerts in the Western style are  not traditional.
[10]
Gamelan's role in rituals is so important that there is a Javanese saying, "It is not official until the gong is hung".
[11] 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 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.
[12] Certain pieces are designated for starting and ending performances or ceremonies. When an "ending" piece (such as "
Udan Mas")  is begun, the audience will know that the event is nearly finished and  will begin to leave. Certain pieces are also believed to possess magic  powers, and can be used to ward off evil spirits.
[11]
Gamelan is frequently played on the radio. For example, the 
Pura Pakualaman gamelan performs live on the radio every Minggu Pon (a day in the 35-day cycle of the 
Javanese calendar).
[11] In major towns, the 
Radio Republik Indonesia employs professional musicians and actors, and broadcast programs of a wide variety of gamelan music and drama.
[13]
In the court tradition of central 
Java, gamelan is often played in the 
pendopo,  an open pavilion with a cavernous, double-pitched roof, no side walls,  and a hard marble or tile floor. The instruments are placed on a  platform to one side, which allows the sound to reverberate in the roof  space and enhances the acoustics.
[14]
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 
banjars, 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. Not only is this where the instruments are stored, but this  is also the practice space for the sekaha (Gamelan orchestra group). The  open walls allow for the music to flow out into the community where the  rest of the people may enjoy it. Inside closed rooms Balinese gamelan  is inaudible, because it easily tresspasses the 
threshold of pain. This does not apply to small ensembles like a gamelan 
gendér.
The sekaha is led by a single instructor whose job it is in the  community to lead this group and to come up with new pieces. When they  are working on a new piece, the instructor will lead the group in  practice and help the group form the new music as they are practicing.  When the instructor creates a new song, he leaves enough open for  interpretation that the group can improvise, so the group will write the  music as they practice it.
There are many styles in Balinese gamelan. 
Kebyar  is one of the most recent ones. Some Balinese Gamelan groups constantly  change their music by taking older pieces they know and mixing them  together, as well as trying new variations on their music. Their music  constantly changes because they believe that music should grow and  change; the only exception to this is with their most sacred songs which  they do not change. A single new piece of music can take several months  before it is completed.
Men and women usually perform in separate groups, with the exception in Java of the 
pesindhen, the female singer who performs with male groups.
[13]
In the twenty-five countries outside of Indonesia that have gamelan,  music is often performed in a concert context or as part of ceremonies  of expat communities
[15]. It may also incorporate 
dance or 
wayang.
 Tuning
The tuning and construction of a gamelan orchestra is a complex process.
[16] Javanese gamelans use two 
tuning systems: 
sléndro and 
pélog. There are other tuning systems such as 
degung (exclusive to Sunda, or West Java), and 
madenda (also known as 
diatonis, similar to a European 
natural minor scale). In central Javanese gamelan, 
sléndro is a system with five notes to the 
diapason (
octave), fairly evenly spaced, while 
pélog  has seven notes to the octave, with uneven intervals, usually played in  five note subsets of the seven-tone collection. This results in sound  quite different from music played in a western tuning system. Many  gamelan orchestras will include instruments in each tuning, but each  individual instrument will only be able to play notes in one. The  precise tuning used differs from ensemble to ensemble, and give each  ensemble its own particular flavour. The intervals between notes in a  scale are very close to identical for different instruments 
within each gamelan, but the intervals vary from one gamelan to the next.
Colin McPhee  remarked, "Deviations in what is considered the same scale are so large  that one might with reason state that there are as many scales as there  are gamelans."
[17]  However, this view is contested by some teachers of gamelan, and there  have been efforts to combine multiple ensembles and tuning structures  into one gamelan to ease transportation at festival time. One such  ensemble is gamelan Manikasanti, which can play the repertoire of many  different ensembles.
Balinese gamelan instruments are commonly played in pairs which are tuned slightly apart to produce interference 
beats,  ideally at a consistent speed for all pairs of notes in all registers.  It is thought that this contributes to the very "busy" and "shimmering"  sound of gamelan ensembles. In the religious ceremonies that contain  gamelan, these interference beats are meant to give the listener a  feeling of a god's presence or a stepping stone to a meditative state.  The scale roughly approximates that of the phrygian mode of the Western  major scale (E-E on the white keys of the piano), with the notes EFGBC  corresponding to the note positions 12356 in the slendro scale used by  most gamelan.
[18]
As well as the non-western octave and the use of beats, 
Javanese gamelan uses a combination of tempo and density known as 
Irama, relating how many beats on the 
saron panerus instrument there are to notes in the core melody or 
balungan; density is considered primary.
[19]
 Notation
Gamelan music is traditionally not notated and began as an 
oral tradition. In the 19th century, however, the kratons of 
Yogyakarta and 
Surakarta  developed distinct notations for transcribing the repertoire. These  were not used to read the music, which was memorized, but to preserve  pieces in the court records. The Yogyanese notation is a checkerboard  notation, which uses six or seven vertical lines to represent notes of  higher pitch in the 
balungan  (core melody), and horizontal lines which represent the series of  beats, read downward with time. The fourth vertical line and every  fourth horizontal line (completing a 
gatra) are darkened for legibility. Symbols on the left indicate the 
colotomic structure  of gongs and so forth, while specific drum features are notated in  symbols to the right. The Solonese notation reads horizontally, like  Western notation, but does not use barlines. Instead, note values and  rests are squiggled between the notes.
[20]
Today this notation is relatively rare, and has been replaced by 
kepatihan notation, which is a cipher system. Kepatihan notation developed around 1900 at the 
kepatihan in Surakarta. The pitches are numbered (see the articles on the scales 
slendro and 
pélog  for an explanation of how), and are read across with dots and lines  indicating the register and time values. Like the palace notations,  however, they record only the balungan part, and to a large extent what  is heard relies on memorized patterns the performers call upon during  performance. However, teachers have also devised certain notations,  generally using kepatihan principles, for the 
cengkok (melodic patterns) of each 
elaborating instrument. In ethnomusicological studies, transcriptions are often made onto a Western staff, sometimes with unusual 
clefs.
[21]
 Influence on Western music
The gamelan has been appreciated by several western composers of 
classical music, most famously 
Claude Debussy who heard a Javanese gamelan play at the 
Paris Exposition of 1889 (
World's Fair). (The gamelan Debussy heard was in the 
slendro scale and was played by Central Javanese musicians.
[22])  Despite his enthusiasm, direct citations of gamelan scales, melodies,  rhythms, or ensemble textures have not been located in any of Debussy's  own compositions. However, the equal-tempered 
whole tone scale appears in his music of this time and afterward,
[23] and a Javanese gamelan-like heterophonic texture is emulated on occasion, particularly in "Pagodes", from 
Estampes (solo piano, 1903), in which the 
great gong's 
cyclic punctuation is symbolized by a prominent perfect fifth.
The composer 
Erik Satie,  an influential contemporary of Debussy, also heard the Javanese gamelan  play at the Paris Exposition of 1889. The repetitively hypnotic effects  of the gamelan were incorporated into Satie's exotic 
Gnossienne set for piano.
[24]
Direct homages to gamelan music are to be found in works for western instruments by 
John Cage, particularly his 
prepared piano pieces, 
Colin McPhee, 
Lou Harrison, 
Béla Bartók, 
Francis Poulenc, 
Olivier Messiaen, 
Pierre Boulez, 
Bronislaw Kaper and 
Benjamin Britten. In more recent times, 
American composers such as 
Henry Brant, 
Steve Reich, 
Philip Glass, 
Dennis Murphy, 
Loren Nerell, 
Michael Tenzer, 
Evan Ziporyn, 
Daniel James Wolf and 
Jody Diamond as well as 
Australian composers such as 
Peter Sculthorpe, 
Andrew Schultz and 
Ross Edwards have written several works with parts for gamelan instruments or full gamelan ensembles. 
I Nyoman Windha  is among contemporary Indonesian composers that have written  compositions using western instruments along with Gamelan. Hungarian  composer 
György Ligeti wrote a piano étude called 
Galamb Borong influenced by gamelan.
American folk guitarist 
John Fahey included elements of gamelan in many of his late-60s sound collages, and again in his 1997 collaboration with 
Cul de Sac, 
The Epiphany of Glenn Jones. Influenced by gamelan,
[25] Robert Fripp used rhythmically interlocking guitars in his duets with 
Adrian Belew in the 
1981–1984 trilogy of albums (
Discipline, 
Beat, 
Three of a Perfect Pair) by rock band 
King Crimson[26][27] and in "
A Connecticut Yankee in King Arthur's Court" on Fripp's album with 
The League of Crafty Guitarists.
[28] The gamelan has also been used by British multi-instrumentalist 
Mike Oldfield at least three times, "Woodhenge" (1979), "The Wind Chimes (Part II)" (1987) and "Nightshade" (2005).
On the debut EP of 
Sonic Youth the track 'She's not Alone' has a gamelan timbre. Experimental pop groups 
The Residents, 
23 Skidoo (whose 1984 album was even titled 
Urban Gamelan), 
Mouse on Mars, 
His Name Is Alive, 
Xiu Xiu, 
Macha, 
Saudade, 
The Raincoats and the 
Sun City Girls have used gamelan percussion. Avant-garde performance band 
Melted Men uses Balinese gamelan instruments as well as gamelan-influenced costumes and dance in their shows. The 
Moodswinger built by 
Yuri Landman gives gamelan–like clock and bell sounds, because of its 
3rd bridge construction. Indonesian-Dutch composer 
Sinta Wullur has integrated Western music and gamelan for opera.
 Influence on contemporary music
In contemporary 
Indonesian music scene, some groups fuse contemporary westernized 
jazz fusion music with the legacy of traditional 
ethnic music traditions of their people. In the case of 
Krakatau and 
SambaSunda, the bands from West Java, the traditional Sundanese 
kacapi suling  and gamelan degung Sunda orchestra is performed alongside drum set,  keyboard and guitars. Other bands such as Bossanova Java were fused  Javanese music with 
bossanova, while the Kulkul band fuse jazz with Balinese gamelan.
The Indonesian singer 
Anggun,  often incorporated Indonesian traditional tunes of gamelan and tembang  style of singing in her works. Typical gamelan tunes can be trace in  several songs in her album 
Snow on the Sahara such as "
Snow on the Sahara", "
A Rose in the Wind", and also in her collaboration works with 
Deep Forest on "Deep Blue Sea" on their 2002 album, 
Music Detected. Philippines born Indonesian singer 
Maribeth Pascua also featuring gamelan tunes in her songs 
Denpasar Moon and 
Borobudur.
Recently, many Americans were first introduced to the sounds of gamelan by the popular anime film 
Akira.  Gamelan elements are used in this film to punctuate several exciting  fight scenes, as well as to symbolize the emerging psychic powers of the  tragic hero, Tetsuo. The gamelan in the film's score was performed by  the members of the 
Japanese musical collective 
Geinoh Yamashirogumi, using their 
semar pegulingan and 
jegog ensembles. Gamelan and kecak are also used in the soundtrack to the video games 
Secret of Mana and 
Sonic Unleashed. The two opening credits of 1998 Japanese 
Anime Neo Ranga use Balinese music (Kecak and 
Gamelan gong kebyar). Each "waking up" of Ranga in the anime uses the Gong Kebyar theme. The musical soundtrack for the Sci Fi Channel series 
Battlestar Galactica features extensive use of the gamelan, particularly in the 3rd season,
[29] as do 
Alexandre Desplat's scores for 
Girl With A Pearl Earring and 
The Golden Compass. 
James Newton Howard, who composed 
Disney's 2001 feature film 
Atlantis: The Lost Empire, chose Gamelan for the musical theme of the Altanteans.
[30]
Loops of gamelan music appear in electronic music. An early example is the Texas band 
Drain's album 
Offspeed and In There,  which contains two tracks where trip-hop beats are matched with gamelan  loops from Java and Bali and recent popular examples include the 
Sofa Surfers' piece 
Gamelan, or 
EXEC_PURGER/.#AURICA extracting, a song sung by 
Haruka Shimotsuki as part of the 
Ar tonelico: Melody of Elemia soundtracks.
