The Fundamentals of Chord Construction
Music Theory: The Basics • 3m 22s
A chord is a combination of two or more notes played at the same time. They’re built on a single starting note called the root. You can create chords from all twelve notes. There are also four basic types of chords in music. For an example, we’ll use G as our root to demonstrate each type of chord:
Major – Has a major third and a perfect fifth above the root
Minor – Has a minor third and a perfect fifth above the root
Diminished – Has a minor third and a diminished fifth above the root
Augmented – Has a major third and an augmented fifth above the root
These shapes are the most common type of chords, and they’re called triads. A triad is a chord made of three notes. Triads have a root note, a third (four half-steps above the root), and a perfect fifth (seven half-steps above the root). Triads are also the foundation for more complex chords, which we’ll explore later in Guitar Super System.

Where Scales Fit In
A musical scale is a set of notes within an octave arranged by their pitch. The ascending or descending interval relationships among the note pitches define every scale.
Musical modes are scales derived from a parent scale, in this case, the Major Scale. Each mode is a slight variation of a scal...
