Triad Chords

The combination of two or more intervals makes a chord. Chords are ordinarily built by intervals of a third.  The simplest chord type is the triad. Triads may be the basis of whole harmonic system.


Members of Triads

Members of Triads
The names “root”, “third” and “fifth” are three members of triads. The root is also fundemental base of any chord. Regardless of any inversions, these names preserve their ability to describe triad chords’ note members.


Inversion of Triads

Inversion of Triads
Lowest note of a triad determines chords’ inversion position.
If a triad has a root factor in lowest note, it is said to be in “root position”.
If a triad has a third factor in lowest note, it is said to be in “first inversion”.
If a triad has a fifth factor in lowest note, it is said to be in “second inversion”.


Harmonic Types of Triads

There are four kinds of triads. These are formed by relation of root note and
other factors of triads’ interval types.
Harmonic Types of Triads

The major and minor triads are consonant chords, because they composed by consonant
intervals.

Diminished and Augmented triads are dissonant, because they have diminished fifth
and augmented fifth which are known as dissonant intervals.
