Song Structure
Understanding E major:
E major has a bright, uplifting character typical of major keys. The Ionian (Major) with minor color in the bridge mode gives it a stable, resolved feeling. This key works well for anthemic rock songs and creates a powerful, confident mood.
Pro Tip: These keys utilize open strings on guitar, making them ideal for powerful, ringing chords. The open strings add natural sustain and harmonic richness.
Primary Chords Used

Notes: E - F# - G# - A - B - C# - D# - E
Application: Primary harmonic foundation for verse and chorus chord progressions
Fretboard Pattern
Chord Progressions
Main Progression
Expansive verse progression that moves through the key of E major with a descending emotional arc, creating the reflective mood of the song
Theory Insight:
This progression creates a specific harmonic movement that defines the song's emotional character. Understanding the relationship between these chords helps in improvisation and songwriting.
Chord Shapes Used:
E
B
C#m
G#m
A
Harmonic Functions:
- E (I):Bright major tonic establishing the optimistic foundation
- B (V):Dominant chord providing forward motion and resolution tension
- C#m (vi):Relative minor adding reflective, melancholy color
Key Techniques
Fingerstyle Chord Melody
AdvancedThe intro uses a fingerpicked chord-melody technique where individual notes from chord shapes are plucked to create a flowing melodic line, blending harmony and melody simultaneously
Uses chords:
See chord diagrams in the Chord Reference section above
Progression:
D - F# - E (arpeggiated chord melody)
Tips:
- • Practice each chord shape individually before connecting them
- • Focus on even finger pressure and consistent volume across strings
- • Use a clean tone with slight reverb for the authentic sound
- • Let notes ring into each other rather than cutting them short
- • Listen to the original recording to internalize the phrasing and timing
Dynamic Strumming with Clean Tone
IntermediateThe verse sections use a controlled strumming approach with clean electric guitar tone, requiring precise dynamic control to move from quiet, intimate verses to full-bodied chorus strumming
Uses chords:
See chord diagrams in the Chord Reference section above
Progression:
E - B - C#m - G#m - A (Verse)
Tips:
- • Control dynamics with strumming hand distance from strings
- • Use the wrist, not the arm, for gentle verse strumming
- • Practice the transition from fingerpicking to strumming smoothly
- • Keep the clean tone crisp - any buzzing is very audible
- • The song's emotional impact comes from dynamic contrast
Barre Chord Transitions
IntermediateSmooth transitions between multiple barre chord shapes across different fret positions, essential for the verse and chorus progressions
Uses chords:
See chord diagrams in the Chord Reference section above
Progression:
B - C#m - G#m - A (verse movement)
Tips:
- • Release finger pressure slightly during transitions, but don't fully lift
- • Use guide fingers to slide between positions when possible
- • Practice each two-chord transition in isolation before chaining
- • The slow tempo makes sloppy transitions very noticeable
- • Focus on getting clean sound on every string of each barre chord
Practice Exercises
Scale and technique exercises in the key of E major. Practice these patterns to build the skills needed for this song.
Intro (Chord Melody)
0:00-0:34Chord Voicing Exercise
John Frusciante's iconic fingerpicked intro, one of the most recognizable guitar intros in rock history, using arpeggiated chord voicings high on the neck
Chord Voicing Exercise
- • Fingerpicked arpeggios using chord shapes at the 9th-10th fret area
- • Clean tone with slight reverb - no distortion
- • Let notes ring and overlap for a harp-like, ethereal quality
Verse
0:34-1:24Chord Voicing Exercise
Reflective verse with gentle strumming building from intimate to engaging, supporting Kiedis's introspective vocal melody
Chord Voicing Exercise
- • Start with very gentle, almost whispered strumming
- • Build dynamics gradually through each verse repetition
- • Barre chords must ring cleanly at this slow 68 BPM tempo
Chorus
1:24-2:08Chord Voicing Exercise
The emotionally powerful the signature section with fuller strumming and the bittersweet F#m-centered progression
Chord Voicing Exercise
- • Strumming opens up to full, ringing chords
- • F#m barre chord must be strong and clear as the anchor
- • Emotional peak of each verse-chorus cycle
Bridge / Outro
3:12-4:24Chord Voicing Exercise
The emotionally climactic bridge and outro section featuring a chromatic descending chord progression with modal mixture, building to the song's most intense moment before the final vocal chants
Chord Voicing Exercise
- • Chromatic descending bass line creates powerful emotional movement
- • A to Am shift is the key moment - major to minor color change
- • Each chord slides down chromatically, building tension

Presence: 6-7 (sparkle and clarity)
Alternatives:
Effects
Distortion:
None for intro/verse; light overdrive for bridge intensity
Reverb:
Medium hall reverb for ambient, spacious sound
Other:
Boss CE-1 Chorus (subtle, for the intro chord-melody shimmer). Clean tone is paramount for this song.
Learning Path
Time Estimate: 3-5 weeks with regular practice
- • Master open E and A chord shapes
- • Practice basic barre chord shapes for B and F#m
- • Learn a simplified strumming pattern for the verse
- • Work on chord transitions at very slow tempo
Time Estimate: 4-8 weeks for solid performance
- • Master all barre chord shapes: B, C#m, G#m, F#m
- • Practice smooth transitions between barre positions
- • Work on dynamic strumming (soft verse to strong chorus)
- • Learn the chorus F#m - E - B - F#m progression with proper feel
- • Add the bridge chromatic descent: A - Am - G6 - Fmaj7 - E
Time Estimate: 6-10 weeks for complete mastery
- • Learn the fingerpicked chord-melody intro note by note
- • Develop smooth transitions between fingerpicking and strumming
- • Add subtle chorus effect for intro authenticity
- • Practice the complete song with full dynamic arc from beginning to end
Practice Notes
Common Mistakes
- • Rushing through the slow 68 BPM tempo - this song needs patience and space
- • Buzzing barre chords due to insufficient finger pressure
- • Playing the intro too rigidly - it should feel free and expressive
- • Not enough dynamic contrast between the quiet verse and full chorus
Practice Routine
- • Warm up with barre chord exercises: B, C#m, G#m, F#m transitions (5 minutes)
- • Practice the intro chord-melody section slowly, note by note (10 minutes)
- • Work on verse strumming with dynamic control at 68 BPM (5 minutes)
- • Practice the bridge chromatic descent: A - Am - G6 - Fmaj7 - E (5 minutes)
- • Play through the full song focusing on the emotional arc and dynamics
Focus Areas
- • Clean barre chord execution at slow tempo
- • Fingerstyle accuracy and tone for the intro
- • Dynamic control from whisper-quiet to full strumming
- • Smooth transitions between fingerpicking and strumming sections
Metronome Work
- • Set metronome to 68 BPM and practice verse progression with half notes
- • Practice barre chord transitions with clicks on beats 1 and 3 only
- • Work on the intro without a metronome first (rubato feel), then gradually add timing
- • Use metronome for chorus section to lock in the rhythmic drive
