Instruments in gamelan gong kebyar offer a wide range of pitches and
timbres, ranging five octaves from the deepest
gongs to the highest key on a
gangsa. The high end can be described as "piercing", the low end "booming and sustained," while the drums as "crisp". Kebyar instruments are most often grouped in pairs, or "gendered." Each pair consists of a male and female instrument, the female being slightly larger and slightly lower in pitch.
See the tuning section in this article for more information. Keyed instruments Most instruments in kebyar are keyed
metallophones, with bronze keys resting on suspended chords, over bamboo resonators. The instruments often have ornately carved wooden frames. The gangsa section in gamelan gong kebyar is the largest section, consisting of 13-14 players. Gangsa instruments are played with a mallet, called a
panggul gangsa. The mallet differs in hardness depending on the instrument and its range. The keys are arranged from low to high, left to right. The key is struck with the hammer in one hand, and damped with the finger and second knuckle of the other hand. The keys can be played in one of three ways: • Strike the key, and let resonate until sound fades. • Strike the key, and damp immediately prior to, or simultaneous with, the striking of the next note in the melody. This is especially good for
interlocking parts. • Strike while damping. This gets a dry, pitched click. The gangsa instruments play elaborate ornamentations (flowers) on the underlying melody (
pokok, or trunk of the tree) of a piece of music. The explosive feeling of the gong kebyar style derives mainly from the dynamic range of these instruments, whose bright, sharp tones can sound anywhere from soft and sweet to extremely loud and aggressive. Each gendered male/female pair of gangsa is also divided into two interlocking melodic parts,
polos (mostly plays on the beat) and the
sangsih (mostly plays off the beat) during
kotekan, which permits extremely rapid, virtuosic, and complex patterns to be played.
Gangsa kantilan There are four kantilan in kebyar, two male and two female.
See gendered instruments within this article. These instruments are the highest sounding in the kebyar ensemble, with its highest note being around C7. It has ten keys, and a range of two octaves, and is played with a wooden hammer. Players often sit on the floor to play this instrument.
Gangsa pemadé There are also four in , two male and two female. These instruments also have ten keys, a range of two octaves, and are played with a wooden mallet, but are exactly one octave lower than kantilan. Players often sit on the floor to play this instrument.
Ugal There is often only one
ugal in the kebyar ensemble, and it is usually female. It is played by one of the leaders of the ensemble. A second, male ugal is sometimes used. The ugal is taller than the other gangsa, and the player sits on a short stool, so as to allow the player to cue the ensemble visually with ease. The instrument also has 10 keys, with a range of two octaves, and is played with a hard wooden mallet, slightly larger than the other and usually with additional ornamentations so the leader's sometimes theatrical cues actively catch the light. Its notes are an octave lower than those of the . The ugals play a combination of gangsa parts and cues, melodic solos, and the underlying melody with flourishes. The first, front ugal cues and plays elements of the polos interlocking gangsa part (the part that plays more often on the beat), and if there is a second ugal, it plays elements of the sangsih part (gangsa notes more often off the beat).
Jublag Higher in pitch than the jegog is the (or ; see related xylophone ). This instrument, like jegog, also requires long resonating bamboo tubes so is often played while sitting on a small stool, and consists of one female/male pair. These instruments have a range of one octave, in between and . Some have five keys (1, 2, 3, 5, and 6) but seven key
jublag are also commonly found in Bali (though gong kebyar ensembles typically do not use notes 4 and 7, using only the pelog selisir scale). It usually plays at submultiples of the
pokok; the keys are struck more frequently than the
jegogan and usually less frequently than the
ugal (playing the
pokok). The
jublag part is often the full
pokok while the
ugal part includes some ornamentations and flourishes; however, the
jublag do not play full kebyar sequences, for example. This instrument is one octave above the
jegogan and overlaps tones with the
ugal.
Jegogan There are two
jegogan (shortened to "jegog" in everyday speech) in kebyar, one male and one female. These instruments have a range of one fifth, and are one octave below jublag. The keys are considerably larger than those of other
gangsa, and are played with a large, cloth-coated, rubber-padded spherical mallet. The jegogan plays the deepest tuned notes in the ensemble, typically playing key notes in the underlying melody of a piece of music instead of every note of that melody.
Vertically suspended gong family Gongs come in different sizes, and provide a structure for phrasing for the music by repeating a four or eight beat pattern. This pattern is called the
gong cycle. Gongs are mounted vertically.
Gong gedé Also referred to as just
gong,
gong gedé is the deepest, and most resonant.
Gede, sometimes written
gde, means 'big' in Balinese. Because it is the largest of the gongs, it is considered to be the most sacred instrument in kebyar. It is never damped, always allowed to decay. Because of its deep tone, it penetrates through the ensemble and can be heard for miles. It is struck with a large, padded mallet.
Kempur A medium-sized gong, the
kempur is very similar to
gong gedé as it has very similar qualities, but is just higher in pitch (about an octave and a fifth higher). It is struck with a large, padded mallet.
Klentong Also known as the
kemong, this is much smaller and higher in pitch than the
kempur. It is struck with a harder mallet than either the
gong gedé or
kempur, which allows it to have a sharper attack.
Kettle gong family Kettle gongs are round, bronze, and pitched. They are often mounted horizontally on suspended chords as part of a frame. Positioned this way, there is an opening on the bottom, slightly beveled bow on top, and a protruding center called the
boss. The kettles are arranged from low to high, left to right. They are generally played with a wooden mallet wrapped in string on one end (to soften the attack) or the end of the mallet, which is bare, finished wood. Mallets are held one in each hand as extensions of pointed index fingers. There are four conventional strikes: • On the boss with the stringed part of the mallet, and immediately released to let it vibrate freely. • On the boss with the stringed part of the mallet but pressed to damp any vibration. • On the bow of the kettle with the wood tip of the mallet, and allowed to ring freely. • On the bow of the kettle with the wood tip of the mallet, but pressed to damp any ringing.
Frame mounted horizontal kettle gongs Reyong Also spelled
reong, this instrument consists of 12 kettles mounted horizontally in a row on a frame. It is played by four musicians, each taking responsibility for 2 to 4 of its kettles. The players, who sit in a row, are split into two groups, the first consisting of the first and third players in the row, and the second consisting of the second and fourth players. Both people in the same group play the same part, but doubled an octave apart. The parts of group one and of group two, when played together, are
interlocking. The
reyong has both melodic and non-melodic percussive roles.
Trompong dancer The
trompong is not usually used in kebyar, as it is associated with older genres such as
gamelan gong gdé. When it is used, however, it is positioned in front of the ensemble, facing the audience. Constructed similarly to
reyong, it consists of 10 kettles, with a range of two octaves. It is played by only one person, and that person may be a leader of the ensemble who sits on a short stool, playing the main melodic line. The trompong is also played by a dancer in dance pieces such as Kebyar Trompong and
Kebyar duduk. Because of the size of the instrument, the melodies are composed to allow one to slowly shift one's position to reach the extremes of its range.
Individual horizontal hand held kettle gongs Tawa tawa The
tawa tawa is a small kettle held in the lap or arm and struck on the boss by a mallet with a soft round head. It plays the beats of the gong cycle and acts somewhat like a metronome.
Kempli or kajar The and are small kettles set over cords strung on a boxlike stand. They are mainly used as tempo keeping instruments. They are usually played with a cord wrapped stick like those of the
reyong and
trompong. The kettle is struck on the boss while damped with the other hand to produce a sharper, dryer sound.
Kelenang Also written
klenang, it is a very small kettle, about 5 inches in diameter, either set on its own stand or held in the hands. It, too, is played with a cord wrapped stick. It plays every second beat of the tempo, usually alternating with the or .
Kajar The
kajar is a small kettle with a recessed boss, held on the lap and played with a hard stick. The
kajar plays accents to important parts of the rhythm.
Primary rhythm instruments Kendang The
kendang is a double-headed drum of jackfruit wood and cowhide. The exterior is shaped like a truncated cone while the negative space of the interior is sculpted like an hourglass. This shape and the cinching action of hide straps creates two distinct, approximate tunings in one drum. Like most gamelan instruments,
kendang are paired: the larger, lead part female,
wadon, and the other male,
lanang. The surfaces inside the
kendang wadon are carved straighter than those in the
lanang, resulting in a more resonant, booming timbre. Much like the
syllables for pitches used for pitched instruments,
kendang have a set of onomatopoetic spoken syllables for each stroke producing a total of 14 types of sound.
Kendang are played with either bare hands only or bare hands plus one mallet. The
kendang wadon player typically tops the hierarchy of the ensemble, setting tempi and aurally cuing transitions like a conductor. The
kendang part is the most complex in gong kebyar, drawing from a rich lexicon of rapid-fire, syncopated patterns to fit the mood and progression of pitched music. The
lanang drummer is responsible for filling in an appropriate
interlocking part.
Kendang players may sit facing the same way,
wadon in front and
lanang behind.
Ceng-ceng Pronounced /t͡ʃeŋ t͡ʃeŋ/, this instrument consists of several small, overlapping cymbals tied to a frame. The frame is often carved to look like an animal, most commonly a turtle, as a mythic turtle is said to carry the island of Bali on its back. The player holds a pair of matching cymbals with bamboo or textile handles, striking the stationary cymbals in quick, even succession or in asymmetrical accents with
kendang or
reyong.
Soft melody instruments Suling One of the two instruments able to bend pitch, the
suling is a vertical bamboo flute.
Suling come in a variety of sizes, from a piccolo-like < 1 ft to a breathy 5 ft. The
suling section doubles and ornaments the melody; the highest register
suling has the freest rein to improvise. The player
circular breathes to allow the pitch to be sustained into a constant tone. A peculiar quality of Balinese
suling, distinct from Sundanese
suling, is a combined vibrato from irregular flexing of the jaw and working of the tongue.
Suling have retained the complete septatonic tuning of court gamelan and can access tones in the pitch gaps of keyed instruments for effect.
Rebab The
rebab is a spike fiddle played with a bow. It is only sometimes used in
kebyar as it is often drowned out by the metallophones. Its melodic line is similar to the
suling, sometimes reaching pitches on a septatonic scale. It has only two strings tuned a Western fourth apart which never touch the unfretted fingerboard. This allows the player to change notes by pressing down on the string, bending the string sideways, sliding, or changing strings. Unlike a Western string bow, the bow of the
rebab is deeper and held underhand like that of a
viola da gamba. The player's thumb applies pressure directly on the hairs to control tension.
Tuning and gender There is no standard pitch in any Balinese music. Generally speaking, all instruments in a gamelan gong kebyar ensemble are made and tuned at the same time. Each ensemble is tuned to itself, making it nearly impossible to remove an instrument from one ensemble to use it in another and have it match pitch. In any ensemble, however, instruments are gendered, and their individual tuning depends on that instrument's gender. Almost every instrument in a kebyar ensemble is paired with a male and female counterpart. Each instrument in a pair is tuned differently from its counterpart, one higher and one lower. Played at the same time, the higher instrument (known as
pengisep or "inhaler") and the lower instrument (known as the
pengumbang or "exhaler"), produce a
beating effect (
ombak) by
sympathetic resonance, creating an overall shimmering, pulsating quality. The female instrument is tuned lower, while the male instrument is tuned higher. For example, one note on a female might be tuned to 220
Hz, while the male might be tuned slightly higher to 228 Hz. Some kebyar ensembles are tuned so that the numban ensemble is tuned so that the beats are significantly faster for higher frequencies, with the lowest
jegog notes nearly a quarter-tone apart. A gendered pair of gangsa will play interlocking kotekan melodies, such that in each pair one interlocking part (polos or sangsih) is on the female and the other on the male instrument. The second pair of that instrument (e.g., ) uses the opposite arrangement, so that there is one instrument of each gender playing each part: female polos, male sangsih, female sangsih, and male polos, for full balance. == Kebyar music ==
