Understanding the half-diminished seventh chord and its inversions is essential for musicians and students studying advanced harmony. This article provides visual guides and audio examples to help you master these complex chords.
Introduction to the Half-Diminished Seventh Chord
The half-diminished seventh chord, also known as the minor seven flat five (m7♭5), is a four-note chord built on a diminished triad with a minor seventh added. It is symbolized as ø or m7♭5.
Its structure consists of a root, a minor third, a diminished fifth, and a minor seventh. This chord is commonly used in jazz, classical, and film music to create tension and resolution.
Chord Construction and Inversions
The half-diminished seventh chord can be played in three inversions: root position, first inversion, and second inversion. Each inversion offers a different sound and function within a progression.
Root Position
The root position places the root note as the bass. For example, Bø (B half-diminished) includes the notes:
- B (root)
- D (minor third)
- F (diminished fifth)
- A (minor seventh)
First Inversion
The first inversion has the minor third as the bass note. For Bø, the notes are:
- D (bass)
- F (diminished fifth)
- A (minor seventh)
- B (root)
Second Inversion
The second inversion features the diminished fifth in the bass. For Bø, the notes are:
- F (bass)
- A (minor seventh)
- B (root)
- D (minor third)

Practical Applications
In jazz and classical compositions, the half-diminished seventh chord often resolves to a dominant or tonic chord, creating a sense of tension and release. Understanding its inversions enhances your ability to voice chords effectively and improvise smoothly.
Experiment with these inversions in your practice to develop a deeper harmonic understanding and improve your overall musicianship.
