Harmony - Chords

 Harmony - when two or more notes are played or sung at the same time.

A chord is a group of three or more notes played at the same time. When a three-note chord consists of the root, the third and the fifth is called a triad.

A triad gets its name from the root of the chord (the note at the bottom).

The most important triads of a major scale are built on the I, IV and V degrees. They are called primary triads or primary chords of the key. These chords contain all the tones of the major scale.
