Wouldn’t it be nice if you could predict which chord would probably come next in a song?
I’ve got some good news for you.
It is possible. Not 100%, but somewhere on the order of 75% to 85% accurate.
That’s because music has FORM — like the skeleton that holds your flesh, muscles, and skin up. If you had no bones — no skeleton — your flesh and all the other parts of you would fall in a heap on the floor. Not a pretty picture. But because you DO have a skeleton, you are able to walk around and pretty accurately predict which way your next step will take you.
It’s the same in music. Music has FORM — a skeleton to hold it up, hold it together. And that skeleton is made out of chords — harmony — the tonal center of the song or piece.
