Gamelan music. American folk guitarist John Fahey included elements of gamelan in many of his late-1960s sound collages, and again in his 1997 collaboration with Cul de Sac, "The Epiphany of Glenn Jones." Influenced by gamelan, Robert Fripp and Adrian Belew used rhythmically interlocking guitars in their duets with each other in the 1981–1984 trilogy of albums ("Discipline", "Beat", "Three of a Perfect Pair") by rock band King Crimson and with "The League of Crafty Guitarists". The gamelan has also been used by British multi-instrumentalist Mike Oldfield at least three times, "Woodhenge" (1979), "The Wind Chimes (Part II)" (1987) and "Nightshade"
Gamelan interference beats are meant to give the listener a feeling of a god's presence or a stepping stone to a meditative state. The scale roughly approximates that of the phrygian mode of the Western major scale (E-E on the white keys of the piano), with the notes EFGBC corresponding to the note positions 12356 in the "slendro" scale used by most gamelan. As well as the non-western octave and the use of beats, Javanese gamelan uses a combination of tempo and density known as "Irama", relating how many beats on the "saron panerus" instrument there are to notes in the
