Since sitting down to work out Durans Save a Prayer last week this has been bothering me a bit. I guess in the great scheme of things it's not important, you know if the bass line works, then why worry?
So: the first chord is D minor, then to F (major, I think).
So to get from the D min to the F the notes on the bass are, I think D, A, G, Fsharp and on to the F.
Now normally if I was jamming with the guitards and there was a Dmin to F progression, I wouldn't consider that F sharp note and instead would choose notes common to both chords or a root/ 5th thing.
So Why does it work?
I know it crops up on a whole load of progressions, but I've quoted this one, as I'm working on it at the moment.
I feel a bit stupid asking this question on here, as I've been playing for years and should probably know, but there you go I've gone and done it now.
