[Intro: High-fidelity underwater ambience, very strong lush reverb and very long dreamy delay. Warm ambient synth pads slowly emerge. Very subtle theremin floats in the distant background. A long sustained wobbly electronic lead enters with a slow smooth pitch bend.] 水の月 揺蕩う影 淡きひかり [Long instrumental space: Let the Otamatone-like lead sustain for a long time with slow glissandos. Wide immersive stereo field. Extended echo tails. No rhythm yet.] 蒼き水 月なき水に つきひとつ [Rhythm enters: Gentle 3/4 healing waltz at 78 BPM. Sparse soft piano and deep gentle sub bass. Keep the vocal cool, emotionless, clear and firmly forward.] 透けた身体 光を纏い 夢を揺蕩う [Rhythmic variation: Keep 3/4 but introduce subtle syncopation and a soft flowing pulse. Gradually widen the ambient synth layers without increasing intensity. No build-up.] [Long instrumental interlude: No vocals. Otamatone-like lead and subtle theremin drift slowly through deep reverb and long delay. Use slow pitch bends and long sustained tones. Keep the atmosphere calm and weightless.] いつしかに わたしも水へ 身を任せ [Rhythmic variation: Return to a gentle flowing 3/4 pulse. Use soft Fmaj7, Fadd9 and F6 colors as an expanded tonic. Keep the same vocal timbre and volume. No emotional change.] 水の月 めを閉じれば まだそこに [Outro: No crescendo, no build-up, no final swell, no key change. Keep the same calm vocal timbre. Final vocal phrase is sustained and cool. The Otamatone-like lead answers with a very long descending glissando.] ただ たゆたう ひかり [Clean sustained ending: Hold the final tone naturally. Keep strong reverb and long delay tails, but do not fade out. End cleanly after the sustained resonance.] [END]
