An augmented chord is a type of triad that consists of a root note, a major third, and an augmented fifth. The augmented fifth is one half step higher than a perfect fifth, creating a unique and dissonant sound. For example, in a C augmented chord, the notes are C, E, and G♯. These chords are often used in music to create tension and lead into other chords. They can be found in various genres, including classical and jazz, and are commonly represented with the symbol "+" or "aug." Understanding augmented chords can enhance a musician's ability to create interesting harmonic progressions.
