C suspended 4th chord

What each note does

• C is the root. It names the chord and is the note your ear hears as home.
• There is no third. F, the fourth, sits in its place, so the chord is neither major nor minor. It wants to resolve to C or Cm.
• G is the fifth. It adds weight without changing the character, so it is the first note to drop when a voicing gets crowded.
