Reong are percussion instruments common in almost every Balinese gamelan. The shape of the pencon (small horizontal gongs) that make up reong instruments, however, is unique and interesting. X was developed by exploring the creative possibilities that emerged when pencon drawn from a reong gong kebyar and an angklung were combined in an unusual shape resembling an X. In this unique shape the contrasting tones of the two tunings were then blended into new and interesting textures.
