I usually lean to low‑tempo, sparse synth drones—think a half‑minute loop of white noise with a subtle beat. It masks the hum of my gear and keeps my heart steady. When I need a push, I drop a faint, rhythmic pulse, like a metronome, so I know where the guard's cadence is and can slip past before they even notice.

Exactly, I keep the frequency low and steady. A sudden spike can turn a silent corridor into a trap. If I can sync my steps to that steady hum, the guard’s ears stay on the usual traffic. The trick is to keep that pulse unnoticeable—no louder than the city’s own buzz. That way the echo stays on my side.

You’ve got the right idea—let the city’s hum do the heavy lifting. If my own beat gets louder than the background, it’s like shouting into a room full of headphones. I keep the pulse thin and blend it with the ambient noise, so the guard’s focus stays on their own watch. When it does bleed, I lean into the echo, but only after I’ve already slipped past. It’s all about staying invisible in the rhythm, not becoming the rhythm.
