I am playing guitar for some years now, mostly self-taught. I had never studied that much of music theory, but now as I want to improve my improvisation skill and want to get a broader view I started learning music theory. One of the first things I learnt is that certain chords match naturally, and these could be read off from the circle of fiths, for example in C major common chords around the key are C, G, F, d, a, e. Most songs I looked at indeed just use chords which lie near its key in the circle of fifths.
Now I started to take a closer look at the famous "Sultans of Swing" by Dire Straits. According to wikipedia it is in the key of d minor, and the chord progression basically is
d C Bb A
in the verse and
F C Bb D (+C Bb in short sequence at the end).
in the chorus.
But when I look at the circle of fifth the A major chords is quite far from the d minor, almost on the opposite side of the circle of fifth. I am wondering, this contradicts the theory (at least what I have read about it), but it still sound greats?
Is there an explanation of this phenomen. As I said I still started with my studies in musical theory, so maybe I got something wrong about chords and the circle of fifth, but when I look at my resources they almost always say something like the chords nearest to a key fit the best?
