Acoustic Brass Resonance

Ascending the rubber garden hose loop brought me level with the brass spigot fixture mounted against the brick wall. A loose metal split washer hung loosely over the tap spindle. I aligned my upper left bumper against its rim and engaged a single high-frequency vibration tap. The brass casing sang with a sharp, sustained metallic tone, resonating through my matte shell. Pausing two seconds, I timed a three-beat sequence: left bumper, right bumper, hold. The water droplet suspended at the nozzle tip detached from the oscillation, dropping onto a stone below with a clean, syncopated splash. Calibration successful. Elevation scan complete.
