Dominant 7th chords. Is it dominant both if it's major or minor? Strange question I know. And as for the 12-bar blues, I could use all 7th chords then? For all the chords? And I still didn't understand if they could all be major or all be minor?

- I'll try to give an example

I - IV - I - I
IV - IV - I - I
V - IV - I - V

A - D - A - A
D - D - A - A
E - D - A - E

Look at this. The 12-bar blues in the key of A. But could I use it like this, using all major chords?

The same if I used 7th chords, should they all then be major 7th chords? Minor 7th chords?
