An augmented chord, often noted as "aug", "+", or "augmented", is a type of chord that consists of a root note, a major third, and an augmented fifth. In practice, this means that the fifth of a major chord is raised by a half step. This chord quality is known for its dissonant and unsettled sound, which creates tension and is often used as a transitional chord to lead into another, more stable chord. Guitarists can envision it as similar to a major chord but with the top note in the triad raised. This alteration provides the augmented chord with its unique tonal quality that can add an interesting character to the music, making it a valuable tool in both harmony and melodic improvisation. Commonly used in jazz, rock, and classical music, it can make your playing stand out by adding a dramatic flair.
