Chord and cord sound the same, but a chord is three or more notes played together while a cord is basically a thick string. You strum a chord, but you tie a cord.

The word chord is related to “agreement,” so a chord is made up of notes that somehow agree with each other. A major chord sounds happy, and a minor chord sounds sad. If a sad song makes you cry, it strikes a chord with you. Here are some musical examples:

A cord is a rope, a strand, something you can tie around a bundle. There are cords in corduroy, a thick cotton fabric with a ridged surface. Some other common cords are in your body — vocal cord, spinal cord, and when you were a tiny baby, an umbilical cord. You’ve probably used an extension cord to plug something in, or maybe even tied a cord around a bundle of recycling. Here are some cords in the wild:

Transverse myelitis produces symptoms involving inflammation along the spinal cord that can cause pain, muscle weakness and paralysis. (Los Angeles Times)

Just remember that the letter “h” is like the extra note you need to make a chord. But a cord goes straight from one place to another.
