A characteristic of Balinese composition is the Gamelan Elektrika, a new electronic gamelan modeled after interlocking of parts; a single line is regularly split between a Balinese Gong Kebyar. The first of its kind, Elektrika con- two instruments and two players resulting in quick, intri- sists of seven instruments acting as MIDI controllers accom- cate rhythms. Additionally, gamelan is based on different panied by traditional percussion and played by 11 or more versions of pentatonic tuning with each gamelan set having performers following Balinese performance practice. Three its own related but distinct tuning. No two gamelans are main percussive instrument designs were executed using a the same [4]. combination of force sensitive resistors, piezos, and capaci- tive sensing. While the instrument interfaces are designed to play interchangeably with the original, the sound and travel possiblilities they enable are tremendous. MIDI en- ables a massive new sound palette with new scales beyond the quirky traditional tuning and non-traditional sounds. It also allows simplified transcription for an aurally taught tradition.
