Augmented sixth chords are a fascinating harmonic device used extensively in Western classical music and jazz. Their unique sound and function create tension and resolution that enrich musical progressions. In this article, we explore audio demonstrations that illustrate the function of augmented sixth chords within various harmonic contexts.
Understanding Augmented Sixth Chords
An augmented sixth chord typically consists of a root, an augmented sixth interval above the root, and a perfect or augmented fifth. Common types include the Italian, French, and German augmented sixth chords, each with slightly different note structures. These chords are usually built on the subdominant or dominant, creating a strong pull towards the dominant or tonic.
Audio Demonstration 1: The Italian Augmented Sixth
In this demonstration, listen to the Italian augmented sixth chord resolving to the dominant. Notice the characteristic augmented sixth interval between the lowered sixth and the root of the chord, which creates a tense sound that resolves smoothly to the dominant harmony.

Audio Demonstration 2: The French Augmented Sixth
This clip features the French augmented sixth chord, which includes a second chord tone—usually the second of the scale—and resolves to the dominant. The added note gives the chord a richer sound, emphasizing its function as a tension-building device.

Audio Demonstration 3: The German Augmented Sixth
The German augmented sixth combines elements of the Italian and French chords, often including a lowered sixth and a chromatic note. This demonstration shows how it functions within a progression, leading to the dominant with a distinctive sound.

Analyzing the Progressions
Each audio example highlights the tension created by the augmented sixth chord and its resolution. These progressions demonstrate how composers use these chords to heighten emotional impact and prepare the ear for a key change or tonic resolution.
Conclusion
Audio demonstrations provide valuable insight into the function of augmented sixth chords. By listening to these examples, students and teachers can better understand how these chords contribute to harmonic tension and release, enriching musical expression across genres.
