The thing I have learned about music in all the years I have studied theory, (several years of study on theory) and played my instruments both with and without lessons. My piano teacher was big on explaining the theory behind the music to make it understandable, and I was in a music theory class and that's all we studied, and worked things out with a piano..... It breaks down as follows.

There are essentially TWO rules in music.

1. There are rules in music that must be followed.
2. There are no rules in music and thou canst doth whatever thou wish.

So, no matter what the key and what you expect to hear or to have happen next, it doesn't matter as long as, in the context of how it is used, it sounds good. No chord or progression is off limits if you can make it work.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
