The Third Ear
What if the instrument were inside your own ear? The melody you hear is one your cochlea makes — a phantom difference tone that no speaker ever plays.
🎧 Put on headphones. Close your eyes. Listen for the low tune.
Two high tones sound together; only their gap carries the melody — and that gap is generated inside you, not the speakers.
● f₁, f₂ played · ◯ phantom = in your ear

Sweep it: the played pitch climbs, but the phantom melody stays put. Find the height where your ear-tone rings loudest.
Best with headphones. Start at low volume and raise gently — these are sustained tones. Stop any time.
