Quadrium - Triads SI Lesson

Introduction

Hello All. My name is Dogukan Ozturk. Welcome to the another SI Lesson by me. In this lesson I am gonna explain the triad chords, and how to construct them. Let's begin.

Triads

Chords can be naturally divided into families of related chords based on a particular triad. A triad is a three-note chord that provides a foundation of harmony. Other notes can be added to a triad to form other chords. Many triads are common chords in their own right, while others tend to appear more often as the basis for other chords. The triad is made up of the root, which is the lowest note in the chord, together with the 3rd and 5th above it. If the root is one of the degrees of a major or minor scale then the triads are given Roman numerals or names identifying that degree, in the following way:

-I (tonic triad)
-II (supertonic triad)
-III (mediant triad)
-IV (subdominant triad)
-V (dominant triad)
-VI (submediant triad)
-VII (leading note triad)
