Bonang
Encyclopedia
The bonang is a musical instrument used in the Java
nese gamelan
. It is a collection of small gongs (sometimes called "kettles" or "pots") placed horizontally onto strings in a wooden frame (rancak), either one or two rows wide. All of the kettles have a central boss, but around it the lower-pitched ones have a flattened head, while the higher ones have an arched one. Each is tuned to a specific pitch in the appropriate scale; thus there are different bonang for pelog
and slendro
. They are typically hit with padded sticks (tabuh). This is similar to the other cradled gongs in the gamelan, the kethuk, kempyang, and kenong
. Bonang may be made of forged bronze
, welded and cold-hammered iron
, or a combination of metals. In addition to the gong-shaped form of kettles, economical bonang made of hammered iron or brass plates with raised bosses are often found in village gamelan, in Suriname
-style gamelan, and in some American gamelan
.
In central Javanese gamelan there are three types of bonang used:
The parts played by the bonang barung and bonang panerus are more complex than many instruments in the gamelan; thus, it is generally considered an elaborating instrument. Sometimes it plays melodies based on the balungan
, though generally modified in a simple way. However, it can also play more complex patterns, obtained by combining barung and panerus patters, such as the alternation of interlocking parts (imbal
) and the interpolation of florid melodic patterns (sekaran
).
A single, l-shaped, row, bonang (kolenang) is also a leading melodic instrument in the Sundanese
Gamelan degung
.
The bonang is similar to the Balinese reong and the single row kulintang
of the southern Philippines and Borneo.
