We say that when you hear a sound you’re hearing vibrations, but what does that mean? A vibration isn’t exactly a thing you can touch. You’re experiencing changes in air pressure, like a barometer, and since there’s only one air pressure at any given time and space, the fact that you can hear two sounds together should give you pause.
It’s only through the virtue of consciousness and perception that the ideas of harmony and dissonance exist at all.
