Chord Progressions

Individual chords become music when they move from one to the next. This week you will learn how chords are built from scales, Roman numeral analysis, and the most common progressions in popular music.

Learning Goals

Build diatonic triads from a major scale (I-ii-iii-IV-V-vi-vii°)
Read Roman numeral chord symbols
Play the I-IV-V-I and I-V-vi-IV progressions
Understand tension and resolution in chord movement

Lesson Content

Diatonic Chords

When you build a triad on every note of a major scale using only notes from that scale, you get seven diatonic chords. In C major:

  • I — C Major (C-E-G) — Tonic, "home"
  • ii — D minor (D-F-A)
  • iii — E minor (E-G-B)
  • IV — F Major (F-A-C) — Subdominant
  • V — G Major (G-B-D) — Dominant, creates tension
  • vi — A minor (A-C-E) — Relative minor
  • vii° — B diminished (B-D-F)

Uppercase Roman numerals = major chords. Lowercase = minor. The ° symbol = diminished.

Common Progressions

  • I-IV-V-I — The most fundamental progression in Western music (rock, folk, country)
  • I-V-vi-IV — The "pop progression" heard in countless hit songs
  • I-vi-IV-V — The "50s progression" (doo-wop, early rock)
  • ii-V-I — The core jazz progression

Tension and Resolution

The V chord (dominant) creates tension that wants to resolve back to the I chord (tonic). This pull is the engine that drives music forward. The IV chord acts as a "stepping stone" between home and tension.

Practice Activities

Activity 1: Play Chord Progressions

On the Synthesizer, play these progressions in C major:

  • I-IV-V-I: C major → F major → G major → C major
  • I-V-vi-IV: C major → G major → A minor → F major

Use the Metronome at 72 BPM, changing chords every 4 beats. Listen to how each progression creates a sense of movement and resolution.

Activity 2: Chord Ear Training Review

Strengthen your chord identification on Intermediate. Knowing chord qualities makes it much easier to hear progressions. Try to get your streak to 10+.

Activity 3: Interval Training — Advanced

If you are scoring 70%+ on Intermediate intervals, try Advanced. This covers all intervals chromatically. Strong interval skills help you hear the movement between chord tones.
