Where the phrase comes from

The idiom comes from music: literally “striking a chord” means playing several notes together on a stringed instrument. Over time, English started using it metaphorically for emotions—like someone “playing” an emotional chord inside you.

Early literal uses appear in the late 1600s, while the emotional/idiomatic sense is recorded from the early 1800s.
