An augmented triad is a type of chord used in music theory, consisting of three notes. It is formed by stacking two major thirds on top of each other. For example, in the key of C, the notes C, E, and G# create an augmented triad. This unique structure gives the chord a distinct, bright sound that can add tension and color to musical compositions. Augmented triads are often used in various genres, including classical and jazz music. They can serve as transitional chords, leading to other chords or keys. Understanding augmented triads can enhance a musician's ability to create interesting harmonic progressions and enrich their compositions.
