Saron

Physical description:
The saron is a metallophone with six or seven keys that rest on a wooden trough, which also serves as resonator. Three instruments belong to the saron family that employ different sizes and pitch registers: the largest size with the lowest register is called demung; the medium size with a medium octave range, saron barung; and the smallest size and highest register, saron panerus or peking. A full ensemble may have two demung, four saron, and two  peking. Another instrument that musically falls in the saron family is slenthem, but physically it is built similar to the gender (i.e. suspended by a cord over tube resonators).

Role in the gamelan ensemble:
For the most part (with the exception of peking), saron instruments play the melodic skeleton (balungan) of a gendhing within the limitation of their melodic ranges. There are other playing styles through which the saron create interlocking patterns. Unlike the other saron, the peking’s melody anticipates and doubles or quadruples the melody of the melodic skeleton (balungan). In some cases, it paraphrases the balungan.
