Chords are built from a scale. This process is called harmonization, and consists of creating chords by stacking scale tones distanced by intervals of third.
If we add 2 intervals of third to a scale note, we obtain chords with 3 notes that could be major, minor, diminished or augmented chords . If we add 3 intervals, we obtain chords composed by 4 notes, and we call them seventh chords.
Chords from major scale
The harmonization of the major scale creates the following chords:
- I the root note, is a major chord
- II is minor chord
- III is minor chord
- IV major chord
- V major chord
- VI is a minor chord
- VII is a diminished chord
Fachords Scales Harmonizer is an interactive guitar music theory application that shows you the harmonization of the major scale and the relative minor scales. It visualizes the various kind of seventh chords generated by the harmonization of a major, harmonic minor, melodic minor and natural minor scales, their structure and the tones composing the chords. The tones of the chords are visualized also on the guitar fretboard.
