Also spelled, "reong", this instrument consists of 12 kettles mounted horizontally in a row on a frame. It is played by four musicians, each taking responsibility for 2 to 4 of its kettles. The players, who sit in a row, are split into two groups, the first consisting of the first and third players in the row, and the second consisting of the second and fourth players. Both people in the same group play the same part, but doubled an octave apart. The parts of group one and of group two, when played together, are interlocking. The "reyong" has both melodic and non-melodic percussive roles.
