Augmented triad: the “eyes widening” harmonic effect
Jacob Collier demonstrates how an augmented triad is formed by stretching the top note of a standard triad. He connects the sound to a physical/emotional sensation—like your eyes widening—showing how harmony can feel embodied.
- •Defines a triad as a three-note chord
- •Explains “augmented” as making the chord bigger by raising the top note
- •Demonstrates the distinct color/tension of an augmented triad
- •Links a harmonic change to a visceral human reaction
- 0:05 – 0:41
Diminished chord: shrinking harmony into unease
He contrasts augmented harmony with diminished harmony, describing a diminished chord as a triad that has been “shrunk.” The sonic result is presented as more unstable and psychologically charged.
- •Defines diminished harmony as compressing/shrinking the triad
- •Demonstrates the characteristic tense, unsettled diminished sound
- •Frames chord quality as emotional narrative, not just theory
- •Highlights how small interval changes dramatically shift feel
- 0:41 – 0:45
Intervals underneath: naming the dissonant building blocks
Collier points to the basic intervals that create these chord colors, calling out a particularly harsh interval (a diminished second). He uses it to illustrate what musicians describe as dissonance.
- •Introduces intervals as the foundation of chords
- •Names an example interval: diminished second
- •Describes the interval as less “friendly” in sound
- •Defines the experience as dissonance
- 0:45 – 1:51
Dissonance isn’t “bad”: it can be devastatingly beautiful
He challenges the simple idea that consonance is good and dissonance is bad, arguing that dissonance can be profoundly beautiful. The key is context and control—how and when tension is introduced and resolved.
- •Rejects the binary of “bad dissonance” vs “good consonance”
- •Claims dissonance can be beautiful and emotionally powerful
- •Emphasizes control of dissonance as an artistic skill
- •Suggests tension increases meaning in harmony
- 1:51
Tension and release: why music moves us
Collier expands from harmony to the broader mechanics of musical emotion: tensions and releases over time. He notes that dissonance/consonance interact with rhythm, repetition, and time to shape the journey of a piece.
- •Music’s emotional impact comes from tension-and-release arcs
- •Harmony (dissonance/consonance) is one major driver
- •Rhythm, time, and repetition also create motion and meaning
- •A musical piece is a path shaped by controlled contrasts
Music mirrors speech and culture: why it naturally affects us
He concludes by arguing that the same ingredients that shape music also exist in speech, culture, and the observable world. Because these patterns are already human and familiar, it’s no surprise that music affects us so deeply.
- •Musical dynamics resemble patterns in speech
- •Cultural rhythms and repetitions parallel musical structures
- •Music reflects observable tensions and resolutions in life
- •Explains music’s impact as rooted in human experience
