The immersive musical work "An-Ki" is a composition rooted in the musiqueconcrète idiom and inspired by Sumerian mythology about the cosmic duality of An (sky) and Ki (earth). The goal is to explore the integration of the musiqueconcrète approach with Dolby Atmos spatial audio technology as the primary compositional medium, to present a purely auditory narrative experience without visual elements. The creation follows the Wallas Model (preparation, incubation, illumination, verification). Raw sound material was recorded from the environment (natural, urban, objects) using Zoom H1n and H3-VR, then digitally manipulated in a Digital Audio Workstation (DAW) using pitch shifting, time stretching, and granular synthesis techniques. The composition of five movements was then arranged and spatialized in 3D using Dolby Atmos Composer software for 7.1.4 format. The result is a 30-minute immersive acousmatic musical work entitled "An-Ki". This work consists of five movements representing symbolic narratives: eternal union, separation and chaos, longing and emptiness, search and memory, and reunion and resolution. Each movement utilizes sound design and 3D spatialization to build a dramatic flow and immersion. This work contributes to a practical exploration of Indonesian experimental music, demonstrating the potential of Dolby Atmos not only as a tool for film, but as a primary creative medium in musical composition. The creation process also provides detailed documentation of the integration of compositional techniques, speaker installation, and system calibration as a unified artistic process.
