A metallophone with 12, 13, or 14 thin bronze keys suspended by rope and posts over tuned tube resonators. The keys are struck with a pair of padded disc beaters, one held in each of the performer’s hands. The instrument produces a full, sustained tone with a soft attack. One gendèr barung is found in common practice sléndro gamelans, two in pélog gamelans. A smaller version of this instrument called the gendèr penerus, which is tuned an octave higher than the gendèr barung, is found in most modernized and modern common practice gamelans.
