Michael, I know something about basic diatonic theory, and how different modes equate to different scale degrees, etc. Normally this would suggest that a chord built on the major third of the scale would be a minor chord. But then I come across a song like "All of Me". The first chord is a major chord on the root. The very next chord is a major chord built on the major 3rd. Obviously, it sounds good, the composer got the effect he wanted; the song is a standard. How do you view this, theory-wise? Is the "tonal center" changing at this chord? Is this just a composer breaking the rules? Is there something explainable happening here? I'm just trying to expand my obviously limited view of the world. Thanks.
