Meaning of Augmented Chords in Music
Augmented chords are a type of chord used in music. They are considered non-diatonic chords because they do not belong to a diatonic scale in any key. An augmented chord is formed by taking a major triad and raising the fifth note by a half step, making it an augmented fifth. Instead of the interval of the 5th being perfect, it is labeled as an augmented 5th.
The symbol for an augmented chord is a "+" sign. For example, a C augmented chord would be written as C+. If the augmented chord has additional notes, such as a seventh or extended chord, the extra notes are added after the "+" sign. For instance, a C augmented seventh chord would be written as C+7 or C+9.
Usage and Examples of Augmented Chords
Augmented chords are less common in popular music, as they have a unique and dissonant sound. However, they can add an extra dimension to an otherwise predictable chord progression Some examples of songs that use augmented chords include Chuck Berry's "School Days," which starts with an F# augmented chord, and The Beatles' "Oh! Darling," which begins with an E+ chord.
In jazz music, augmented chords are used more frequently. Wayne Shorter's song "Juju" is known for its abundant use of augmented chords. Augmented chords can add tension and create a gritty sound, which can be desirable in certain musical contexts.
Conclusion
In summary, augmented chords are non-diatonic chords formed by raising the fifth note of a major triad by a half step. They have a unique and dissonant sound and are less commonly used in popular music but are more prevalent in jazz.
