Are you a music enthusiast who wants to delve deeper into the world of music theory? If yes, then you have probably heard about harmonic music theory. Harmonic music theory is a branch of music theory that deals with the study of chords, their progressions and how they work together to create harmonies.

What is Harmonic Music Theory?

Harmonic music theory is a study of how different chords work together in a piece of music. It involves analyzing chord progressions, identifying chord functions, and understanding how these elements create harmony. Harmonic music theory helps musicians understand the underlying structure of the music they are playing or composing.

Chords and Harmony

Chords form the backbone of harmony. They are created by combining three or more notes played simultaneously.

Chords can be major, minor, augmented or diminished, depending on their interval structure. In harmonic music theory, chords are classified by their function within a key.

The Circle of Fifths

The circle of fifths is an essential tool in harmonic music theory. It shows the relationship between different keys and their corresponding chords.

The circle consists of twelve key signatures arranged in a clockwise direction. Each key signature represents a different note on the keyboard.

Chord Progressions

Chord progressions are an integral part of harmonic music theory. They refer to the sequence in which chords are played in a piece of music. Chord progressions create tension and release within a song, making it more interesting to listen to.

Common Chord Progressions


Harmonic music theory is a fascinating subject that every musician should have a basic understanding of. It helps musicians create more interesting and complex compositions while also giving them the ability to analyze existing music. With knowledge of chord progressions, key signatures, and chord functions, musicians can create harmonies that are both pleasing to the ear and emotionally captivating.
