The most common chords are triads, which are built by adding the third and fifth notes in the scale above a starting note (or root). For example, in C major, the triad built on C contains:
- C (the root)
- E (the third note above C; often called just "the third")
- G (the fifth note above C; often called just "the fifth")
This is called the C major triad.
Make the C major triad below:
As with major scales, most people hear major triads as "happy" or "uplifting."
