i–VI–III–VII: Epic Minor Rock
Bm–G–D–A is a go-to minor-key engine because it feels wide and heroic without complex harmony. In Roman numerals it is i–VI–III–VII, which creates a strong sense of motion while avoiding the full dominant cadence, so the loop stays open for riffs and layered production. The chord changes also share plenty of common tones, letting you keep a top-line hook stable while the harmony recontextualizes it. That is why this progression works in modern metal, cinematic rock, worship-influenced anthems, and indie choruses. For guitar, try power chords with octave melodies on top; it keeps the riff aggressive but singable. For writing, place your melody on F# over Bm and let it become the third of D; that pivot makes the hook feel glued to the harmony. If you need more tension, add F#7 before returning to Bm.

Play it on guitar
Start slow, keep your right hand steady, and aim for clean changes on the downbeats. Once it’s comfortable, add a groove and increase tempo.
Capo suggestion: try capo 2 and play in A shapes for open chords.

Roman numerals & theory
Roman numerals describe the chord’s function relative to the key. This helps you transpose the “shape” to any key without memorizing new chord names.
Variations (keep the progression, change the feel)
- • Add 7ths for color (try maj7 on I, m7 on vi, and V7 before resolving).
- • Use a sus4 resolve on the V chord (e.g. Gsus4 → G) to create tension and release.
- • Change the rhythm instead of the chords: try anticipations (hit the next chord on the “and” of 4).
- • Arpeggiate the top notes to create a hook while the harmony stays the same.
- • Borrow a darker chord for contrast (in a major key, try iv for one bar before returning).
