D – A – Bm – G (I–V–vi–IV in D)

DIAVBmviGIV

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

  1. 1Loop D–A–G–G until the major chords are automatic.
  2. 2Learn the four-string Bm (x-2-4-4-3-x) before the full barre.
  3. 3Drill A→Bm and Bm→G in isolation at a slow tempo.
  4. 4Insert Bm into the full D–A–Bm–G loop once the shape holds for four beats.
  5. 5Capo as needed; this progression is a cover-song workhorse in many keys.

Where you'll hear it
