Augmented and Diminished Chords

The video tutorial explores different types of triads in music theory, including major, minor, augmented, and diminished chords. It explains how augmented chords expand the fifth by a half step and how diminished chords reduce the fifth by a half step. The tutorial also compares these chords, highlighting that augmented and diminished chords are symmetrical, dividing the octave evenly. The video concludes with a preview of the next lesson, which will introduce the concept of adding a seventh to the chords.

What is the result of raising the fifth of a major triad by a half step?

• An augmented chord

• A major seventh chord

• A minor chord

• A diminished chord

How is a diminished chord formed?

• By adding a seventh to a major triad

• By stacking two major thirds

• By lowering the fifth of a minor triad

• By raising the third of a major triad

What is the structure of a diminished chord?

• A minor third followed by a major third

• Two minor thirds stacked

• A major third followed by a minor third

• Two major thirds stacked

Which type of chord divides the octave evenly into thirds?

• Minor chord

• Diminished chord

• Major chord

• Augmented chord

What characteristic do augmented and diminished chords share?

• They both divide the octave evenly

• They are both major chords
