Rythm structure is 4 quarter notes per bar.
But with chord change in the middle of each bar.
The Verses (Dm C Bb A) use a andalusian cadence.
Here is a possible version for the main riff.
The melody uses some triplet notes to give this special groove.
whereas the chord strumming follows quarter and 8th notes
