How To Play Notes That Aren't There

Combination tones are... weird. There's no better way of putting it. They're fake notes that don't actually exist, but your ear and your brain hear them anyway. How is that possible? Well, it all comes down to some clever combinations of real frequencies that balance out to create a ghost pitch that no one's playing but can still be heard. You can even use them to create faint, imaginary melodies hiding within real sounds, to make a musical secret that only exists in your audience's mind. See? Told you they were weird.
