Triads are three-note chords that are built by stacking notes in thirds. There are four types of triads: major, minor, augmented, and diminished. Major triads are built with a root, major third, and perfect fifth, while minor triads have a root, minor third, and perfect fifth. Augmented triads have a root, major third, and augmented fifth, and diminished triads have a root, minor third, and diminished fifth. Triads are the building blocks of harmony in Western music and are essential for understanding chord progressions and harmonic function. **

The secondary dominant is a chord that is not diatonic to the key but is used to create tension and lead to a chord within the key. It is typically the V chord of a chord other than the tonic, and it is used to temporarily establish a new key center before resolving back to the original key. In music theory, the secondary dominant is often notated with a Roman numeral followed by a slash and the chord it is leading to, such as V/V for the secondary dominant of the dominant chord. This chord progression technique is commonly used in classical and popular music to create harmonic interest and drive the listener's ear towards a specific resolution. **
