The panerusan instruments or elaborating instruments are one of the divisions of instruments used in Indonesian gamelan. Instead of the rhythmic structure provided by the colotomic instruments, and the core melody of the balungan instruments, the panerusan instruments play variations on the balungan. They are usually the most difficult instruments to learn in the gamelan, but provide the most opportunity for improvisation and creativity in the performer.[3]

Panerusan instruments include the gendér, suling, rebab, siter/celempung, bonang, and gambang. The female singer, the pesindhen, is also often included, as she sings in a similar fashion to the instrumental techniques. As these include the only wind instruments, string instruments, and wooden percussion instruments found in the gamelan, they provide a timbre which stands out from most of the gamelan.[3]

The notes that the panerusan instruments play are largely in melodic formulas known as cengkok and sekaran. These are selected from a huge collection which every performer carries in his head, based on the patet, mood, and traditions surrounding a piece.[3]
