1. Choosing Bamboo
Bamboo is the raw material of the Angklung. Selected on the basis of age ie at least 4 years and not more than 6 years and cut in the dry season from 9 am to 3 pm today. After cutting the base of the bamboo tree, measuring approximately 2-3 jengkaldari ground level, the bamboo should be kept for about 1 week, so the bamboo benar2 not contain water.
After a week, bamboo must be separated from its branches. And cut to specific sizes. Then, the bamboo should be kept for about a year to prevent from pest. Some procedures are: bamboo by soaking in a puddle of mud, pond or river, can also be smoked in the hearth way (diunun), and modern procedures: using a formula of certain chemicals.
2. Angklung Parts
Angklung consists of 3 parts:
Voice Tube
The most important part of an Angklung, the sound tubes that produce intonation. From the local process can produce intonation.
Framework
Framework tube to place standing.
Base
Serves as a frame of voice tube.
3. Process tuning
-------------------------------------------------- ------------------------------
Formation of tube sound
This is the process of forming a blade bamboo tube sound.
Process tuning
This is the process of blowing the bottom of the tube angklung and equate his voice to the instrument tuner.
The main process of tuning
This is the process of tuning the sound by raising and lowering the tone with the ring tone. And this is also the process raise the tone by cutting the top a little, and lower the tone with menyerut both sides of the tube with a knife blade.
How to use the tool Tuner:
To use the tuner, we must consider both the lights on the left and right of the panel, and also the needle pointer.
For example, if you will create a tone of "F", you have to shake angklung while considering both of light which will light up simultaneously, and for the needle that will show the number "F".
4. Final Stage
After each sound has a tone tube, tube must be placed into the frame and tied with rattan ropes.
5. Maintenance
Tune / Men-stem Angklung
little by little until you reach the desired sound. 2. If the sound Angklung be lower, should end Angklung (side B) is cut little by little so that her voice
became normal again.
Storage and Maintenance Angklung For a given that Angklung made of bamboo materials, construction or power does not like metal, so we need good maintenance and storage. Good Angklung made from bamboo that has been through good quality control process. Long storage before being processed into Angklung bamboo must be at least one year old. Drying process is working for Angklung bamboo made to produce accurate sound / loud and less susceptible to pest termites. Angklung age when the treatment is good to reach 10 years.
Here are the steps that can be done to maintain the instrument Angklung:
Once Angklung arrived at a new place, get open and hang on the pole standard that has been provided. Storage in a cardboard box / place closed more than 7 days can result in a change of voice and penjamuran on bamboo. Storage Angklung preferably by hanging, not stacked. Angklung storage should be in a dry place and not humid with temperatures ranging from 25-33 C. Do not store in the open Angklung that get sunlight or rain directly. To maintain Angklung from penjamuran and termites, use anti-termite and fungal production SAU regular 2 weeks once the spraying process. To maintain sound quality do the tuning / re-tuning Angklung periodically. Angklung displacement from where we (Saung Angklung Udjo) to a new place (where the buyer) will slightly affect the voice (usually up around 30 Hz), because conditions are not the same air temperature. To overcome this, the stem re-(re-stem) needs to be done. For Angklung stored in hot temperatures with temperatures> 30 C sometimes causes a slight crack on the base of the tube. This does not interfere with the sound, and handling are given enough wood glue
