This is a simple ii V I exercise in key of D with a Blue Bossa Feel.
You can repeat this loop again and again. This exercise uses a lot of 5th.
Go listen to the actual Blue Bossa and check out the actual chord progression and practice it.
It will be something like this: Cm7 Fm7 Dm7(b5) G7 Cm7 and etc.
Have Fun!
