Can an Augmented Sixth Lead Straight to Tonic?

Augmented sixth chords are intriguing harmonic entities that add color and tension to musical compositions. They are typically used as chromatic predominant chords that resolve to the dominant. However, there is a question regarding whether an augmented sixth chord can lead directly to the tonic, bypassing the dominant altogether. In this article, we will explore this topic and examine the possibilities of an augmented sixth chord resolving to the tonic.

Understanding Augmented Sixth Chords

Before delving into the resolution possibilities, let us first understand the nature of augmented sixth chords. Augmented sixth chords do not have a root in the traditional sense. Instead, they are identified by the interval of an augmented sixth between two specific notes, namely “le” and “fi.” This interval creates the distinctive sound and character of augmented sixth chords.

There are three main types of augmented sixth chords: Italian, French, and German. Each type has its unique construction and voice leading characteristics, but they all share the common feature of containing the augmented sixth interval. These chords are typically used as chromatic alterations of predominant chords, adding tension and harmonic richness to the music.

Resolution to the Dominant

The dominant is the most common destination for augmented sixth chords. They have a natural tendency to resolve to a root-position dominant chord. This resolution creates a strong sense of harmonic tension and prepares the listener for the eventual resolution to the tonic.

Resolution to the Tonic

While the dominant is the primary destination for augmented sixth chords, it is worth noting that they can also be used to resolve directly to the tonic. In fact, resolving to the tonic is the second most popular destination for augmented sixth chords after the dominant. This resolution creates a unique and dramatic effect in music.

When an augmented sixth chord resolves directly to the tonic, it bypasses the dominant and creates a sense of surprise and resolution. This harmonic progression can be particularly effective in creating tension and release in musical compositions.

Harmonic Intensification and Chromaticism

Augmented sixth chords have a versatile nature and can be used to create harmonic intensification through chromaticism. By introducing chromatic alterations, such as the augmented sixth interval, composers can add rich and unexpected harmonies to their compositions. Augmented sixth chords can serve as a vehicle for chromaticism and lead directly to a root-position dominant chord, intensifying the harmonic progression.

Conclusion

In conclusion, while augmented sixth chords are typically used as chromatic predominant chords that resolve to the dominant, they can also be employed to resolve directly to the tonic. Augmented sixth chords add color, tension, and harmonic intensification to musical compositions. Their resolution to the tonic creates a unique and dramatic effect, bypassing the dominant and surprising the listener. Augmented sixth chords showcase the creative possibilities of chromaticism and contribute to the rich tapestry of harmonic language in music.
