Understanding Functional Harmony: An Introduction

Considered the ‘grammar’ of music, functional harmony is a crucial component of Western music. This theoretical framework acts as a guide for composers and musicians, demonstrating how to arrange and resolve chords to establish a musical flow and direction.

The Core Principles of Functional Harmony

Functional harmony works on the belief that each chord within a key plays a function—creating tension, resolution, or stability. These roles are generally categorized into three groups: tonic, dominant, and subdominant.

Tonic Function: The tonic function is the key’s home base. It represents stability and resolution. For instance, in the key of C Major, the tonic chord is C.
Dominant Function: The dominant function generates tension that seeks resolution to the tonic. In the key of C Major, the dominant chord is G.
Subdominant Function: The subdominant function lies between the tonic and dominant. It introduces variety and can lean towards either the tonic or dominant. In the key of C Major, the subdominant chord is F.

Importance of Chord Progressions in Functional Harmony

In functional harmony, chord progressions have a significant role. They are the chord sequences that establish a tension-release narrative throughout a music piece.

The II-V-I progression is one of the most common chord progressions in functional harmony, serving as a fundamental element in jazz and various other music genres.

This tool is invaluable for understanding functional harmony as it depicts the natural movement tendency in Western music – from the dominant function to the tonic.

Harmonic Analysis: Utilizing Functional Harmony

Harmonic analysis involves deciphering a music piece’s harmonic structure. It includes identifying the key, chords, their functions, and how they progress through the piece.

Applying functional harmony principles in harmonic analysis helps musicians comprehend complex musical structures and make informed decisions about performance or composition.
