An augmented triad is a type of chord made up of three notes: the root, the major third, and the augmented fifth. For example, in a C augmented triad, the notes are C (root), E (major third), and G# (augmented fifth). The augmented fifth is one half step higher than a perfect fifth, creating a unique sound that is often described as bright or tense. Augmented triads are commonly used in various music genres, including classical and jazz. They can create a sense of tension that resolves to other chords, making them effective in chord progressions. Musicians often use augmented triads to add color and complexity to their compositions.
