Gamelan adaptations of Beach Surgery emerge from the instrumental and cyclical traditions of Indonesian ensembles, particularly in Bali and Java. The most documented work is Siklus (Cycle), a 47-minute composition by Gamelan Çudamani, premiered at the 2021 Jakarta Arts Festival. The piece translates the novel's recursive structure—its insistence on perpetual return—into the tuning systems and cyclical repetitions native to traditional gamelan.
The ensemble, working without narrative text, interprets Beach Surgery through sonic analogy: the pelog and slendro scales' incommensurable relationship mirrors the glitch, the moment where the story's two halves "do not compute." Five movements correspond to stages of the cycle, with metallophone patterns building, fragmenting, and reassembling in strict recurrence. A sustained gong drone (the ageng) punctuates the work—interpreted by the ensemble as the Kármán line, the boundary Katita hears "rubbing against the walls of the world."
The recording circulates privately among scholars; a 2023 conference presentation confirmed the work's artistic intent, though no commercial release has been authorised. [citation needed] The piece suggests how non-Western instrumental traditions can address the franchise's deepest structural impossibility: the unresolvable seam between order and chaos.
