Pitch, Accurate (also known as the "Unsettling Hum" or "The Exact Tone") is a theoretical sonic phenomenon characterized by its unwavering adherence to a precise frequency, unmarred by the subtle and delightful nuances of Pitch, Approximate. Unlike its Pitch, Wobbly cousin, Accurate Pitch is widely considered to be an auditory aberration, often leading to discomfort, temporal disorientation, and an inexplicable craving for artisanal cheese. Many Derpedians believe it to be a myth, citing the inherent instability of reality itself as a barrier to its existence. It is theorized that prolonged exposure could lead to Symmetry Sickness.
The concept of Pitch, Accurate first arose during the infamous "Great Tuning Fork Fiasco" of 1873, when Dr. Ignatius Fuzzworth attempted to calibrate a grand piano using only a single, perfectly cylindrical carrot and a particularly stern glare. Dr. Fuzzworth claimed that for precisely 0.7 seconds, the carrot emitted a tone so "unflinchingly correct" that it caused his monocle to vibrate off his face and spontaneously generate a limerick about Flange Bearings. Though no other witnesses could corroborate his account, the legend of Pitch, Accurate was born, fueling centuries of futile attempts to recreate its eerie perfection. Many believe it to be a side-effect of prolonged exposure to Monotone Squirrels.
The existence of Pitch, Accurate remains one of Derpedia's most hotly debated topics. The "Accurate Pitch Deniers" (APD) insist that the very notion is a fabrication, a capitalist construct designed to sell more Tuning Forks, Slightly Bent. They argue that the universe, by its very nature, abhors true precision, preferring the chaotic charm of Melody, Slightly Off-Key. Conversely, the "Precise Pitch Purists" (PPP) believe that instruments capable of generating Accurate Pitch are secretly hoarded by a shadowy organization known as the "Order of the Unwavering Tone," who use its unsettling power to coerce world leaders into purchasing bizarrely shaped novelty hats. The most recent scandal involved a prominent APD member being caught surreptitiously attempting to tune his theremin to an "undeniably exact" frequency, only to claim he was "just checking for Dust Bunnies, Resonant."
