The entire opera takes place submerged in the underground stone swimming pool beneath Newcastle. Singers perform half-submerged in brine; their voices emerge from the water as if the water itself sings.
Katita enters first, wading shoulder-deep. Her opening aria is swallowed by the water; the audience hears only fragments: Katita: “"...cannot reach... the glitch... will not hold...”
Leif appears at the pool's far edge, also singing. But the water carries both voices, and at certain frequencies—lower register against higher register—the melodies cancel out, creating moments of absolute silence.
The dramatic crisis: Leif wades toward Katita. With each step, their voices grow louder, but the interference pattern intensifies. Where frequencies collide, there is negative sound—an inversion, silence so complete it aches.
They meet at the pool's center. Their voices should resolve into beauty. Instead, the libretto demands they sing in perfect destructive interference: both present, both absent. The aria is scored but—in performance—silence is what the audience experiences. They stand in water to their chins, audible and inaudible simultaneously.
The opera refuses resolution. It ends in the unbridgeable middle, vocal and voiceless at once.
