Gendèr

• 1. Introduction

  ›

  A gendèr holds ten to fourteen tuned metal bars, each suspended over its own resonator of bamboo or metal. A player taps them with a mallet of wooden disks, and a note rings out, sustained until a hand reaches back to silence it. This is one of the central instruments of Balinese and Javanese gamelan music, and its sound spans a little more than two octaves. Five notes fill each octave, which means the seven-note pélog scale cannot be played whole. Some pitches are simply left out, chosen according to something called the pathet. Why would a musician build an instrument that deliberately omits notes? Why does a single gamelan need not one gendèr but three? And what makes playing it with two mallets harder than it looks? These questions open onto a world of tuning, technique, and the quiet discipline of dampening a string of metal.

• 2. Three Instruments, One Ensemble

  ›

  Three gendèr sit inside most gamelans, and each is locked to a different tuning. One is built for the sléndro scale. A second serves the pélog scale in the pathet called nem and lima. A third is reserved for pélog pathet barang. Because five notes fill each octave while pélog carries seven, the instrument can never reach every pitch, so the pathet decides which notes survive and which are dropped. A separate gendèr exists for each of these tuning choices rather than retuning a single frame. The arrangement means a gamelan must keep multiple gendèr on hand to move between the modes a piece may demand.

• 3. Relatives In Metal And Bamboo

  ›

  The Balinese gangsa shares the gendèr's most distinctive trait: an individual resonator tucked under every key. The saron is close kin too, carrying a set of tuned metal bars, though its resonance comes from a single trough rather than separate chambers. The Javanese slenthem belongs to the same family while sitting at the opposite end of its range, pitched lower and built with fewer notes. Set against these neighbors, the gendèr stands out for the way its hands behave. The two hands sometimes move in parallel motion, but they often play contrapuntally, two lines running against each other rather than together.

• 4. The Discipline Of Dampening

  ›

  Dampening is important to most gamelan instruments, and on the gendèr barung played with two mallets it becomes far more demanding. A struck note keeps ringing, so the player must silence it the moment the next note sounds. The same hand that hit a key must turn back and quiet it immediately after striking a new one. One trick is to hold the mallet at an angle, so a single motion can dampen one key while playing another. Even then the hand may need a small pause to manage both tasks at once. The technique sits at the heart of what makes two-mallet playing a test of control.

• 5. Barung And Panerus

  ›

  Two gendèr appear together in some types of gamelan, each spanning roughly two and a half octaves. They are the gendèr barung and the gendèr panerus, with the panerus pitched an octave higher. In Gamelan Surakarta, the panerus plays a single line of melodic pattern, following an approach similar to the siter. The barung takes the slower part, yet the more complex one, weaving separate right and left hand lines. Those two lines come together at intervals the tradition names kempyung, roughly a fifth, and gembyang, an octave. The gendèr also comes in three sizes with their own names. The largest is the jegogan, followed by the jublag and the penyacah, while a pair of ten-bar gendèr is called giying.

• 6. Loud And Soft Ensembles

  ›

  The gamelan divides into two ensemble types, the loud-playing and the soft-playing, and the gendèr belongs to both. The soft-playing style gathers voices alongside instruments like the gambang, celempung, rebab, gendèr panerus, and gendèr barung. The loud-playing style turns instead to the gong ageng, siyem, kempul, kenong, kethuk, kempyang, engkuk-kemong, and the bonang and saron families, along with the gendèr slenthem, the kendhang family, and the bedhug. Across both settings the gendèr plays semi-improvised patterns called cengkok, which elaborate upon a point called the seleh. These patterns stay relatively fixed, yet a player can vary them to suit the style, pathet, irama, mood, and skill at hand.

• 7. Leading From The Cengkok

  ›

  The cengkok repertoire for the gendèr runs more developed and more specific than the patterns given to most other elaborating instruments. This depth gives the gendèr barung a quiet authority within the ensemble. It is likely to cue changes in parts or in irama, the rhythmic density of a piece. That role grows especially clear when the rebab is absent, since the rebab usually leads the ensemble. The gendèr barung may even play the buka, the opening that sets a piece in motion.
