Borrowed chords come from the parallel key - the major or minor scale that shares the same root. In C major, you can borrow chords from C minor. They're not "wrong" - they're intentional.
It's like borrowing an ingredient from another cuisine. You're cooking Italian, but you reach for a Japanese ingredient that happens to work perfectly. Unexpected, but it adds colour that the original pantry doesn't have.
How borrowing works
In a major key, some chords from the parallel minor can be dropped in for a darker, more emotional sound. The most commonly borrowed chords are:

Compare each borrowed chord against what you'd normally expect in C major.
bVII - Bb major vs diatonic V - G major
bVI - Ab major vs diatonic vi - A minor
iv - F minor vs diatonic IV - F major
Where you hear them
Borrowed chords are everywhere once you know what to listen for:
- - bVII - Rock, pop, EDM. Gives a powerful, modal lift.
- - bVI - Film scores, epic moments. Think Hans Zimmer.
- - iv - Bittersweet moments. "Creep" by Radiohead uses IV -> iv.
- - bIII - Psychedelic, dreamy. Common in classic rock.

Why borrowed chords matter
Diatonic chords give you a solid foundation, but they can start to feel predictable. Borrowed chords let you break the rules deliberately - adding surprise and emotional depth without leaving the key entirely.
Key takeaway
Borrowed chords come from the parallel key (same root, opposite mode). The most common are bVII, bVI, bIII, and iv. They add colour and surprise while still sounding intentional.
Next: secondary dominants - borrowing the V -> I pull and pointing it at any chord in the key for extra tension.
