I-IV-V Progression
The most fundamental chord progression in Western music - a three-chord pattern that forms the backbone of countless songs across all genres.
Theory Fundamentals
Harmonic Functions
- •I (Tonic): Home base, stability, resolution
- •IV (Subdominant): Movement away from home, preparation
- •V (Dominant): Tension that demands resolution to I
- •Pattern: Stability → Movement → Tension → Resolution
- •Voice Leading: Strong bass movement by fourths and fifths
C Major Example
- •I: C Major (C-E-G)
- •IV: F Major (F-A-C)
- •V: G Major (G-B-D)
- •Chord Progression: C - F - G - C
- •Roman Numerals: I - IV - V - I
Guitar Applications
Basic Chord Positions
I-IV-V in C Major
Open position chords:
I - C Major
Tonic - Home
IV - F Major
Subdominant - Movement
V - G Major
Dominant - Tension
Music Notation
Practice Notes:
- • Focus on smooth chord transitions
- • F major barre chord can be challenging
- • Practice with steady strumming rhythm
- • Listen for the resolution from G back to C
I-IV-V in G Major
Alternative key with easier fingerings:
I - G Major
IV - C Major
V - D Major

Advanced Applications
Common Variations
Popular I-IV-V variations:
- • I-IV-I-V (return to tonic before dominant)
- • I-IV-V-V (extended dominant tension)
- • I-I-IV-V (extended tonic opening)
- • I-IV-V-IV (plagal cadence ending)
- • I-IV-vi-V (deceptive resolution)
Chord Extensions
Add sophistication with extensions:
- • V7: Add seventh to dominant (G7 instead of G)
- • Vsus4: Suspended fourth creates tension
- • I6: Add sixth for color (C6 instead of C)
- • IVmaj7: Major seventh on subdominant
- • V/V: Secondary dominant (D7 to G)
Key Transposition
I-IV-V in common guitar keys:
- • A Major: A - D - E
- • D Major: D - G - A
- • E Major: E - A - B
- • F Major: F - Bb - C
- • Bb Major: Bb - Eb - F

Scale Relationships & Theory
Diatonic Relationships
Scale Degrees in C Major
- • I (C): 1st degree - Tonic
- • IV (F): 4th degree - Subdominant
- • V (G): 5th degree - Dominant
- • Strong pull from V back to I
- • Perfect 5th intervals in bass line
Circle of Fifths Movement
- • Bass moves: C → F (up 4th)
- • Bass moves: F → G (up 2nd)
- • Bass moves: G → C (up 4th)
- • Creates strong harmonic momentum
Voice Leading
Common Tones
- • C major (C-E-G) to F major (F-A-C)
- • C is common tone
- • F major (F-A-C) to G major (G-B-D)
- • No common tones - all voices move
- • G major (G-B-D) to C major (C-E-G)
- • G resolves to C (leading tone)
Smooth Voice Leading
- • Keep common tones when possible
- • Move other voices by step
- • B (leading tone) resolves up to C
- • Creates smooth harmonic flow
