IV-I Plagal Cadence
The gentle resolution that closes hymns, seals gospel songs, and adds a sense of peaceful finality - the plagal cadence moves from subdominant to tonic without dominant tension, delivering calm arrival rather than dramatic resolution.
Theory Fundamentals
Harmonic Functions
- •IV (Subdominant): Warm, open sound that gently departs from home without creating dominant tension
- •I (Tonic): The point of rest and resolution - home base where the cadence settles
- •Relationship: A soft, tension-free resolution - the subdominant descends to the tonic without leading-tone pull
- •Interval: Root movement of a perfect fourth downward (F down to C) or perfect fifth upward
- •Why It Works: IV and I share common tones and the motion avoids the tritone found in V7-I, producing a calm, hymn-like sense of closure
C Major Example
- •IV: F Major (F-A-C)
- •I: C Major (C-E-G)
- •Chord Progression: F - C
- •Roman Numerals: IV - I
- •Common Tone: C is shared between both chords, anchoring the gentle resolution
Guitar Applications
Basic Chord Positions
IV-I in C Major
Open position chords:
IV - F Major
Subdominant - Departure
I - C Major
Tonic - Resolution
Practice Notes:
- • Start on F major and resolve to C major - listen for the calm, settled feeling
- • Keep your 1st finger barring fret 1 on F, then release into the open C shape
- • Play F for 2 beats, then let C ring for 2 beats to hear the plagal resolution
- • Try singing 'A-men' over the F-C change to internalize the cadence
IV-I in G Major
Open position chords:
IV - C Major
Subdominant - Departure
I - G Major
Tonic - Resolution
Practice Notes:
- • C to G is one of the most beginner-friendly plagal cadences on guitar
- • The ring finger can remain on the 3rd fret as a pivot between both shapes
- • Strum C for a full measure, then resolve to G and let it sustain
- • This key is excellent for accompanying vocal 'Amen' endings
Advanced Applications
Common Variations
Ways to expand the plagal cadence framework:
- • IV-I as a song ending tag after an authentic cadence (V-I then IV-I)
- • IVMaj7-IMaj7 for a lush, jazz-influenced plagal resolution (FMaj7 to CMaj7)
- • iv-I (minor plagal cadence) using Fm to C for a bittersweet, cinematic color
- • IV-I with added 9ths and suspensions for modern worship and ambient textures
- • IV5-I5 power chord version for a rock-style plagal ending
Key Transposition
IV-I in common guitar keys:
- • C Major: F - C
- • G Major: C - G
- • D Major: G - D
- • E Major: (barred A shape) - E
- • F Major: Bb - F
Rhythm & Feel Ideas
The plagal cadence adapts to many musical styles:
- • Slow whole-note sustain for hymn and choral endings - let each chord breathe
- • Gentle arpeggiated fingerpicking for introspective singer-songwriter resolutions
- • Gospel shuffle with rhythmic anticipation on the IV chord before settling on I
- • Ambient swells with volume knob or tremolo picking for cinematic fade-to-rest
- • Layered vocal harmonies singing 'Amen' over the IV-I for full choral effect
Musical Examples & Famous Uses
Hymns & Gospel
The "Amen" Cadence in Hymns
Nearly every traditional hymn ends with a IV-I plagal cadence sung as 'Amen'
The congregation sings 'A-' on the IV chord and '-men' on the I chord, creating the most recognized cadence in Western sacred music
"Let It Be" (Ending) - The Beatles
The famous C-F-C ending gesture is a plagal cadence in C major
McCartney's gospel-influenced songwriting uses the IV-I resolution to give the song its sense of peaceful acceptance and closure
Gospel & Worship Music Tradition
The plagal cadence is the harmonic backbone of gospel endings
From traditional spirituals to modern worship, the IV-I resolution provides a sense of divine peace and completion that the stronger V-I cannot match
Rock, Pop & Beyond
"Creep" (Ending) - Radiohead
The song's final chord change uses a plagal-like resolution for emotional weight
The subdominant-to-tonic motion gives the ending a wistful, unresolved-yet-settled quality
Classic Rock Song Endings
Many rock songs add a IV-I tag after the final chorus for a definitive close
Bands from The Who to Led Zeppelin use the plagal cadence as a final punctuation mark before the last sustained chord
Film & TV Scoring
Composers use the plagal cadence for scenes of resolution, redemption, and peace
The gentler quality of IV-I (compared to V-I) signals emotional settling rather than dramatic triumph - perfect for quiet, meaningful moments
Practice Exercises
🎸 Cadence Recognition
- • Play V-I (G to C) then IV-I (F to C) back to back and compare the resolution quality
- • Practice identifying plagal cadences in hymns, gospel songs, and pop recordings
- • Play the IV chord for 4 beats, then resolve to I and sustain - notice the calm arrival
- • Try the plagal cadence in C major (F-C), G major (C-G), and D major (G-D)
- • Record yourself playing IV-I and V-I cadences, then listen back to hear the difference
🎵 Chord Transitions
- • Alternate F to C every 4 beats at 60 BPM, focusing on clean transitions
- • Speed up to 2-beat changes, keeping the resolution smooth and unhurried
- • Practice the F barre chord shape until every string rings clearly before resolving
- • Work on pivot fingers: keep the index finger anchored when moving from F to C
- • Try the same transitions in G major (C to G) with the ring finger as pivot
🎭 Creative Application
- • Add a IV-I tag to the end of any song you already know for a peaceful conclusion
- • Write a short 4-bar phrase ending with F-C and notice how it closes the idea
- • Experiment with the minor plagal cadence: play Fm to C and compare the mood
- • Layer the IV-I cadence with different dynamics - try pianissimo for a whispered ending
- • Record a loop of I-IV-V-I and then add a IV-I tag at the end for extra closure
Practice Exercises with Notation
Exercise 1: Basic Plagal Cadence in C Major
Practice the fundamental IV-I resolution with sustained chords in C major:
Practice Tips:
- • Hold F major for 4 beats, then resolve to C major for 4 beats
- • Let the C chord ring fully and listen for the sense of peaceful arrival
- • Sing 'A-men' (F on 'A-', C on '-men') to feel the cadence in your voice
- • Repeat until the resolution feels natural and the F chord is clean on every string
Exercise 2: Gospel Plagal Cadence in G Major
Practice the plagal resolution with a gospel feel using C to G in open position:
Practice Tips:
- • Play C major (IV) with a gentle strum for 2 beats, then resolve to G major (I) for 2 beats
- • Add a slight ritardando (slowing down) on the IV chord before resolving to I
- • Try adding a bass walk-down from C to G: C note, B note, then land on G chord
- • Use this cadence to end any progression you practice today
Exercise 3: Plagal Cadence with Extended Chords
Enrich the IV-I cadence using major 7th voicings for a lush, modern sound:
Practice Tips:
- • Play FMaj7 (IV) resolving to CMaj7 (I) in C major for a jazz-influenced plagal sound
- • Let each chord sustain for a full measure so the extended harmonies ring out
- • Compare the sound of FMaj7-CMaj7 to the basic F-C cadence and note the added warmth
- • Use this voicing as a sophisticated ending tag for ballads and jazz standards
Scale Relationships & Theory
Harmonic Foundation
Scale Degrees
- • IV (F): 4th degree - Subdominant, a warm departure that sets up the resolution
- • I (C): 1st degree - Tonic, the home chord and ultimate resting point
- • Root movement by perfect 4th downward (F down to C) or perfect 5th upward
- • Unlike V-I, the IV chord contains no leading tone that pulls to the tonic
- • This absence of tension creates a floating, peaceful quality unique to the plagal cadence
Why IV-I Feels Gentle, Not Dramatic
- • The IV chord shares a common tone with I (C appears in both F major and C major)
- • No tritone interval exists between IV and I (unlike the V7-I authentic cadence)
- • The resolution feels like settling or descending rather than snapping into place
- • The lack of leading-tone tension makes IV-I ideal for peaceful, reverent endings
Voice Leading & Theory
Common Tones (F and C major)
- • F major (F-A-C) resolves to C major (C-E-G)
- • C is the common tone shared between both chords, providing continuity
- • A moves down to G (whole step) - smooth descending voice leading
- • F moves down to E (half step) - the smoothest possible resolution
- • All voices move by step or stay put, producing extremely smooth voice leading
Plagal vs. Authentic Cadence
- • Authentic cadence (V-I) has the leading tone pulling up a half step to the tonic root
- • Plagal cadence (IV-I) lacks this leading tone, so resolution is softer and less urgent
- • The plagal cadence is often used after an authentic cadence as a final 'Amen' tag
- • In classical theory, IV-I alone is considered a weaker cadence - but in gospel and pop it stands powerfully on its own
