[Instrumental narrative: an aurora unfolding across the night sky] [Scene 1: Silent polar night] [Extremely low intensity. Vast darkness and immense open space. Almost imperceptible atmospheric resonance. Sparse distant glass-like overtones appear and disappear.] [Scene 2: The first trace] [A faint luminous presence slowly emerges. Very delicate sustained tones begin to shimmer. A single floating tone gradually bends and changes pitch. The sound remains extremely sparse and suspended.] [Scene 3: The arc appears] [A thin luminous arc forms across the sky. Slow gliding tones begin to move horizontally and upward. Glass-like harmonics, vibraphone resonance and distant bowed textures interact in long, fluid phrases.] [Scene 4: The aurora begins to move] [Intensity increases gradually. Flowing glissando movements become wider and more expressive. Layers of shimmering overtones begin to drift across the stereo field. Subtle low flute resonance gives depth beneath the high luminous textures.] [Scene 5: Curtains of light] [The aurora expands into large flowing waves and vertical curtains. Stronger dynamic movement. Ondes Martenot-like gliding tones, glass harmonics, vibraphone resonance and layered atmospheric textures move independently, creating a vast supernatural soundscape.] [Scene 6: The sky becomes alive] [Highest intensity. Broad waves of luminous sound sweep across the entire space. Rapid but fluid changes of pitch and texture suggest enormous curtains of light moving overhead. Distant wordless human humming and subtle a cappella human resonance merge deeply with the upper harmonics as an atmospheric instrumental texture.] [Scene 7: The light dissolves] [Intensity gradually falls. The moving light becomes slower and more transparent. Individual glass-like tones and distant gliding sounds remain suspended in the darkness.] [Final scene: The last trace] [Only a few faint high overtones remain. The vast night slowly returns to silence.] [Fully resolved ending]
