Building Chords Ch. 3 - Part 4 (Triads, with 4's and 6's)

In this instructional video, the instructor demonstrates how adding fourths and sixths to triads can create new sonic textures and even transform a chord into a different one, a phenomenon he calls the "Chicken‑or‑Egg" scenario. Beginning at 0:00, the introduction outlines this concept. At 4:38, the use of a root or power chord as a reference point is explained. From 6:06 to 10:54, major triads with added fourths are explored, including their use in classic rock and variations that avoid suspended fourths. The section from 21:10 to 26:12 focuses on distinguishing between E and A major chords with added fourths. At 32:20 and 40:45, the instructor examines major triads with augmented fourths, reusing ideas and presenting a favorite combination. The minor triad with added fourths is covered from 53:12 to 1:01:06, followed by minor triads with augmented fourths at 1:06:20. Moving to sixths, major triads with added sixths are discussed from 1:11:05 to 1:15:58, including the question of whether they are major sixth or minor seventh. Additional notes are added to major sixths at 1:23:12. Minor triads with added sixths are examined from 1:26:36 to 1:37:33, addressing whether they are minor sixth or minor seventh flat five, and from 1:41:06 to 1:46:53, minor triads with added flat sixths are considered, questioning whether they are minor flat six or major seventh. Finally, other triads incorporating these extensions are showcased from 1:46:53 to 1:53:24, including diminished triads with fourths or minor pentatonic variations.
