Layer 2 (Modern Rhythm Foundation): Organic pop drum kit, clean sub-bass. Layer 3 (Harmonic Glue): Acoustic piano block chords, lush orchestral string section swells; Vocals: Female duet, clear soprano voices, ancient-style tone, delicate and poised delivery, alternating narrative voices; Mood: Nostalgic and devoted, evoking imagery of ink brush paintings and candlelight in a pavilion, exploring the emotional archetype of loyal devotion through fleeting time; Highlight: the narrative contrast created by the alternating lead vocals of the two distinct female singers.",
