Cor, pictured above on rebab (2-string violin) with gamelan ensemble 'Widosari', and on gong with the Nieuw Ensemble. Siter, a string instrument plucked with the thumbs, was Cor's main intrument in gamelan. Mostly Cor played Mangkunegaran-style traditional music, but also contemporary pieces, such as by Balinese composer I Wayan Sadra. Widosari toured in Europe as well as performed 'Wayang Revolusi' in Java.
