Chords in Major and Minor Keys - TWO MINUTE MUSIC THEORY #47

The video tutorial explores different types of triads in music theory, focusing on augmented and diminished chords. It explains how augmented chords are formed by expanding the fifth and how diminished chords are created by reducing the fifth. The tutorial also compares these chords with major and minor triads, highlighting their symmetrical and asymmetrical properties. The augmented chord divides the octave into thirds, while the diminished chord divides it into fourths.
