Triads

Triads

Triads are constructed using the first three odd-numbered notes of a seven-note scale (with exceptions), or by moving up twice in skips or thirds from any note within a seven-note scale (as in a harmonized scale). The quality of the triad is determined by its comparison to a paralell major scale. If it matches the first, third and fifth note, it is a major chord [ maj, mj, ]. Alterations from this chord are described in chord formulas, which are used to create chord symbols.
