And those who are looking for the mysterious sound that people with perfect pitch hear, your already looking too hard. There are levels to each pitch; the first level is the timbre. Which is the sound of the instrument that you’re playing. Like a guitar has a stringy sound. Timbre is the surface level. The level below that is your “perfect pitch sound”. This is the sound of the actual pitch of the note. People who have perfect pitch listen to this more discretely when naming a pitch or any other ability of pitch perception. And guess what. Everybody hears it, when your tuning your instrument this is the sound your tuning by, if you learning a song you heard on your stereo, “this is what your listening for, whether you know it or not”. The other levels are the vibration of the notes (no, you don’t hear every vibration like C has roughly around 440 vibrations per second). But you get an idea, sort of like looking at a helicopter propeller spin, you don’t see each time it goes around but you get a blurred spin of it. Same exact way with these vibrations. The last audible level of a pitch is its overtones and they are very low in volume, pretty hard to hear. And those who take the David Lucas Burge super course can mistake these for the “perfect pitch sound”. But if you are hearing these overtones, you already have a great ear. You’re just looking in the wrong place.
