🎵 What Is This Progression?

The I-IV-V progression is the fundamental base of rock and roll and popular music since the 1950s. They are the three major chords that every major key contains, creating a simple, direct, universally recognizable progression.

Why is it so important?

1. Maximum simplicity: Only 3 chords, easy to learn for absolute beginners.
2. Rock and roll foundation: Practically all 50s-60s rock uses this progression.
3. Ascending energy: I→IV→V creates an upward movement of tension.
4. Clear resolution: V→I is the strongest perfect cadence in Western music.

🎓 Related Theory

Harmonic Function

I        →      IV       →       V       →      I
Tonic        Subdominant    Dominant     Tonic
(Home)      (Preparation)    (Tension)   (Resolution)

• I (Tonic): Stable, starting point.
• IV (Subdominant): Upward motion, creates anticipation.
• V (Dominant): Maximum tension, demands resolution to I.
• I (Final tonic): Perfect resolution, sense of closure.

Key difference vs. I-V-vi-IV:

• I-IV-V: Ascending tension (I→IV→V), clear resolution.
• I-V-vi-IV: Immediate tension (I→V), deceptive cadence (vi), then preparation (IV).

I-IV-V is more "predictable" and direct, ideal for simple and effective rock.

Perfect Cadence (V→I)

The V→I resolution is the strongest cadence in Western music:

• Tritone resolves: In the V chord (e.g., G), B (major 7th) wants to rise to C, and F (4th) wants to fall to E.
• Sense of closure: V→I sounds like "question→answer" or "tension→rest".

In C major:

G (V): G - B - D
       ↓   ↓   ↓
C (I): C - E - G

Guide tones: B→C (ascending semitone), F→E (descending semitone in extended context).

Scale-Degree Analysis

In C major:

Chord	Degree	Notes	Function	Feel
C	I	C-E-G	Tonic	Stable
F	IV	F-A-C	Subdominant	Preparation
G	V	G-B-D	Dominant	Maximum tension
C	I	C-E-G	Tonic	Resolution
