Why Do Some Chord Progressions Instantly Feel Emotional? (What’s Actually Happening Theoretically?)

[Daniel_uk]

Hey everyone,

I’ve been learning music theory for a while, and something still confuses me. Certain chord progressions — like I–V–vi–IV or vi–IV–I–V — immediately sound emotional or powerful, even when played with simple triads on a piano.

What exactly is happening in music theory that creates that emotional effect? Is it just familiarity from pop music, or is there something deeper going on with harmonic function, voice leading, or tension and resolution?

I’d love a breakdown that explains what’s actually happening under the hood rather than just “it sounds good.”

Thanks!
