D – A – Bm – G (I–V–vi–IV in D)
The 'axis of awesome' progression in D — bright, driving, and the standard introduction to the Bm barre chord in context.
Why this progression matters
I–V–vi–IV is one of the most-used pop progressions of the last few decades. In D, it introduces Bm — many players' first practical barre — while keeping D, A, and G comfortable.
Practice note
Use the small (4-string) Bm at first so the loop never stalls; upgrade to the full barre as it stabilizes.
Bottleneck change: A → Bm
How to practice it
- 1Loop D–A–G–G until the major chords are automatic.
- 2Learn the four-string Bm (x-2-4-4-3-x) before the full barre.
- 3Drill A→Bm and Bm→G in isolation at a slow tempo.
- 4Insert Bm into the full D–A–Bm–G loop once the shape holds for four beats.
- 5Capo as needed; this progression is a cover-song workhorse in many keys.
Where you'll hear it
- Modern pop and rock hits built on I–V–vi–IV
- Bright acoustic covers in D
