Mistake 3: Confusing Guitar Strings With Guitar Chords

A guitar has strings, and a guitarist plays chords.

  The two words describe completely different things.

Mistake 4: Forgetting the Figurative Use

The expression is strike a chord, not strike a cord.
Correct:

This means the story created a strong emotional connection.

A Simple Memory Trick

One of the easiest ways to remember the difference is:
Chord has an H for harmony.
Think:
C + H = Chord = Harmony
This is not a formal linguistic rule, but it is a useful memory trick.
For cord, think about a cable or rope.
So:
Cord → cable
Chord → harmony
If you remember those two associations, you will rarely confuse them again.
