Gamelan Angklung

In Bali, an ensemble of angklung is called gamelan angklung (anklung). While the ensemble gets its name from the bamboo shakers, these days most compositions for Gamelan Angklung do not use them. An ensemble of mostly bronze metallophones is used instead.

While the instrumentation of gamelan angklung is similar to gamelan gong kebyar, it has several critical differences. First, the instruments are tuned to a 5-tone slendro scale, though actually most ensembles use a four-tone mode of the five-tone scale (an exception would be five-tone angklung from the north of Bali.) Secondly, whereas many of the instruments in gong kebyar span multiple octaves of its pentatonic scale, gamelan angklung instruments only contain one octave, though some five-tone ensembles have roughly an octave and a half. The instruments are often considerably smaller, and hence more portable when used in cremation rituals. The musicians often play in a procession as the funeral bier is carried from the cemetery to the cremation site, in addition to playing music to accompany the ceremony.

The structure of the music is similar to gong kebyar. Jublag and jegog carry the basic melody, which is elaborated by gangsa, reyong, ceng-ceng, drum, and flute. A medium sized gong, called kempur, is generally used to punctuate a song's major sections. And although most older compositions generally do not employ gong kebyar's more ostentatious virtuosity and showmanship, many Balinese composers have created kebyar-style works for gamelan angklung, often featuring dance.

HOW TO MAKE AN ANGKLUNG

THE BAMBOO ELECTIONangklung

Bamboo is the material of an Angklung. It is elected by its age. It has to be at least 4 years old and not more than 6 years old. It is cut on the dry season, between 9 am in the morning to 3 pm at the afternoon. After being cut at its base for about 2-3 span of the hand, it will be stored for about 1 week, so that the bamboo will contain less water.

After a week, the bamboo will be separated from its branches. It will be cut into certain various sizes. Then, will be stored for about one year to keep it from termites. Some of the procedures are: by sinking out the bamboo beneath mud field, pool or river, also by smoking it at the fireplace, and the modern procedure: by using a certain liquid chemistry formula.

2. SHAPING PART OF AN ANGKLUNG

Each Angklung consist of 3 parts:

The Voice Tubes
The Voice Tubes are the most important of an angklung, which produce the intonation made. Tuning process makes the intonations.

The Frame
Frame is supporting the voice tubes to stand inside the hollow space.

The Base
It is function as the frame of the voice tubes.

3. TUNING THE VOICE TUBE PROCESS

Half-Done Process
Shaping the bamboo become laths of voice tube.

Resonance Tuning Process
Blowing the lower part of an angklung to the floor and measuring it to the tuner.

Main Voice Tuning Process
Tuning the voice by increasing and decreasing the tone by strike voice. Increasing the tone by cutting its upper parts slightly, and decreasing the tone by shaping both voice laths with shaping knife.

How to Use a Tuner:

Make an attention to both of the lamps at the left and the right of the panel, and also the pointer needle.

For example, if you're going to make an "F" tone, so that when the angklung is shaking, both of the lamps will flame together, and the pointer needle will point the "F" letter.
4. FINISHING

After each of the voice tubes has its tone, then it will be put into the frame laths and being str

Angklung

Angklung is a musical instrument made out of two bamboo tubes attached to a bamboo frame. The tubes are carved so that they have a resonant pitch when struck. The two tubes are tuned to octaves. The base of the frame is held with one hand while the other hand shakes the instrument rapidly from side to side. This causes a rapidly repeating note to sound. Thus each of three or more angklung performers in an ensemble will play just one note and together complete melodies are produced. Angklung is popular throughout Southeast Asia, but originated from Indonesia (used and played by the Sundanese since the ancient times).
