Augmented Chord Progression: A sequence of chords incorporating augmented triads, where the fifth note is raised by a half step, creating a dissonant and unresolved sound.

Context and Significance

Augmented chord progressions are valuable in music for their ability to introduce tension and an unexpected quality to compositions. Commonly utilized in genres like jazz and classical music, these progressions offer a unique texture that can enhance musical narratives. Musicians often employ augmented chords to evoke a sense of drama or to transition between more stable harmonic structures, making them a versatile tool in both improvised and composed works.

Historical Background

The use of augmented chords dates back to the late Romantic period, where composers began experimenting with dissonance and harmonic ambiguity. This exploration paved the way for greater harmonic complexity in the 20th century, with composers like Debussy and Ravel incorporating augmented chords into their works. This period marked a shift from traditional harmony, allowing augmented chords to become a staple in modern composition techniques.

Examples

In Franz Liszt’s “Faust Symphony,” augmented chords are used to convey the inner turmoil of the characters. Jazz musicians, such as Thelonious Monk, have also embraced augmented chord progressions to push the boundaries of harmonic exploration. These progressions can be found in modern film scores, where they are employed to heighten suspense or create an ethereal atmosphere.
