Borrowed Chord
- Definition
- A borrowed chord is a chord taken from a parallel key or mode, such as borrowing from the minor key while writing in major, rather than from the song's main diatonic scale.

In practice
Every major key has a parallel minor key sharing the same tonic, and vice versa. A borrowed chord pulls a chord from that parallel scale and drops it into an otherwise diatonic progression, creating a moment of unexpected color. Because the borrowed chord still shares the same tonic, it feels connected to the song even though it technically doesn't belong to the main key's scale.
This technique is common at emotionally charged moments, such as the final line of a chorus or the turn into a bridge, where a writer wants a flash of unexpected darkness or brightness without fully changing key. Used sparingly, a borrowed chord stands out precisely because the rest of the song stays diatonic.
Example
In a chorus written in C major, a writer swaps the expected F major chord for F minor just before the final line, borrowing from C minor to add a brief shadow of sadness before the progression resolves back to C.
