Part 4/7:
Moving on from notes, Andrew delves into chords — groups of notes played simultaneously that evoke emotional responses in listeners. Triads, which consist of three notes based on root, third, and fifth intervals, are the building blocks of most chords in music.
Andrew simplifies the classification of chords into two main categories: major, usually perceived as cheerful, and minor, recognized for its somber qualities. He further elaborates on chord progressions, using a numerical system that ties chords to scale degrees, allowing composers to convey varying emotional landscapes through music.
