Part 3/9:
He points out that despite its apparent complexity, the chord contains two separate augmented triads built in major thirds—C augmented (C-E-G#) and D-flat augmented (D-flat-F-A). Recognizing these intervals—particularly the perfect fifths outside these triads—helps establish the chord’s basic shape and range.
Step 2: Recognize Recognizable Intervals and Outer Notes
Rick advocates focusing on the outer notes of a chord—the bass and the top voices—to determine the overall harmonic function. For instance, in the C augmented over D-flat augmented example, Dylan detects the outer notes, which are separated by a perfect fifth, indicating a layered chord structure.
