Instrument numbers 078 to 082 comprise a set of bossed gongs. Cords tied diagonally in the bottomless wooden frame support the instrument. This gong stands higher than the other gongs, and sounds an octave higher than 075. The gongs are struck on the boss with a mallet made of a wooden stick whose end is wrapped tightly with a cotton rope. When struck, a crisp, penetrating sound is produced. One set consists of five gongs, each of which is tuned to one pitch of the slendro scale. Used as a colotomic instrument in gamelan ensembles.
