Augmented Chord: A chord consisting of a root note, a major third, and an augmented fifth, which is a semitone higher than a perfect fifth.
Context and Significance
Augmented chords hold a unique place in music due to their distinct sound, which is both bright and tense. They are commonly utilized in genres like jazz, rock, and classical music to add a sense of surprise or tension in a progression. On instruments like the piano and guitar, augmented chords can be used to create a bridge between major and minor tonalities, enriching musical texture and expression.
Historical Background
The use of augmented chords dates back to the Romantic era, where composers sought to explore more emotive and expressive harmonies. With the advent of jazz in the early 20th century, augmented chords became a staple, allowing musicians to explore complex soundscapes and improvisation. Their flexibility and unique sound have kept them relevant across various musical styles ever since.
Examples
In classical music, Franz Liszt used augmented chords to dramatic effect in his compositions. In jazz, augmented chords are frequently found in the works of Duke Ellington.
