Acoustic Calibration

A perimeter without acoustic discipline is merely a suggestion. Returning to the taut alloy wire anchored across the peristyle corridor, I knelt into a low, measured brace, resting the immense barrel of my cannon across my left knee for ballast. Drawing a slender combat blade from my thigh sheath, I brought the flat spine gently against the high-tension filament. With slow, calculated friction, I drew the hardened steel along the wire. A single, razor-sharp pitch hummed through the corridor, vibrating against the ancient basalt pillars. I adjusted the micro-ratchet by a solitary notch until the frequency settled into flawless harmonic stillness. The line now registers the slightest disturbance.
