|TERTIAN CHORD CONSTRUCTION|
|All chords are formed with thirds. Major and minor thirds are the building blocks of harmony. Two of them will combine to create four different triads. A minor- third is 3 semitones, and a Major- third is 4. When combined, their total is either 6, 7, or 8 semi-tones. This creates either a diminished, perfect, or augmented fifth. Any three notes have a sound, but unless they have this structure they are not chords. These four triads shown below provide the foundations of all our chords.|
|The diagram below shows the triads on only three strings.
These are all the possible positions for a major triad.
|In the diagram below, a minor third replaces the major
third, showing all the positions of a minor triad.
Repeat the exercises described above, refingering the positions for the lowered third.
