Song Structure
Understanding F# minor (intro riff) / A major (verse and chorus):
F# minor (intro riff) / A major (verse and chorus) has a bright, uplifting character typical of major keys. The Aeolian (Natural Minor) for intro/riff; Ionian (Major) for verse/chorus mode gives it a stable, resolved feeling. This key works well for anthemic rock songs and creates a powerful, confident mood.
Pro Tip: Power chords (5ths) work exceptionally well in this key for rock/metal, as they avoid the major/minor quality and focus on raw power.
Primary Chords Used
Scale Patterns in F# minor (intro riff) / A major (verse and chorus)
F# natural minor
Notes: F# - G# - A - B - C# - D - E - F#
Application: Foundation for the iconic intro riff and solo sections; provides the dark, driving quality
Fretboard Pattern
Chord Progressions
Main Progression
The verse/chorus progression in A major, a timeless chord movement that provides the anthemic, uplifting quality beneath Ozzy's vocal melody
Theory Insight:
This is one of the most popular progressions in modern music. The vi chord adds emotional depth, creating a bittersweet quality that works in both uplifting and melancholic contexts.
Chord Shapes Used:
A
E
F#m
D
Harmonic Functions:
- F#5 (i in F# minor):Dark tonic pedal for the intro riff, establishes the heavy metal foundation
- A (I in A major):Bright tonic of the relative major, anchors verse and chorus sections
- E (V):Dominant chord providing strong resolution tension in both keys
Key Techniques
Tritone-Based Intro Riff
AdvancedRandy Rhoads's iconic intro riff built on an F#5 power chord with a tritone interval (augmented 4th/diminished 5th), combining rapid alternate picking with the most dissonant interval in music for a driving, unsettling effect
Uses chords:
See chord diagrams in the Chord Reference section above
Progression:
F#5-based single-note riff with tritone interval
Tips:
- • Start at half speed (70 BPM) and gradually build to 138 BPM
- • Focus on clean alternate picking before adding speed
- • The palm muting pressure controls the tone - too heavy kills sustain, too light loses punch
- • Use a metronome religiously - the riff must be metronomically precise
- • Practice the tritone interval leap in isolation before integrating
Fast Alternate Picking
AdvancedRapid alternate picking technique essential for the intro riff and verse rhythm, requiring precise down-up-down-up motion at 138 BPM with palm muting control
Progression:
Single-note alternate picking across all riff sections
Tips:
- • Economy of motion is critical - minimize pick travel distance
- • Keep your wrist relaxed; tension is the enemy of speed
- • Practice with a clean tone first to hear picking inconsistencies
- • Set a metronome and only increase tempo when the current speed is effortless
- • Take breaks to prevent repetitive strain - speed builds over weeks, not hours
Classical-Influenced Solo Phrasing
ExpertRandy Rhoads's revolutionary approach of blending classical music techniques with rock guitar, featuring sequenced scale runs, arpeggiated patterns, and precise legato phrases that defined a new era of guitar playing
Uses chords:
See chord diagrams in the Chord Reference section above
Progression:
Over F#m - D - A - E solo backing progression
Tips:
- • Break the solo into 4-bar phrases and learn each individually
- • Randy's vibrato comes from the wrist, not the fingers - practice this specifically
- • The classical sequences follow specific intervallic patterns - analyze the theory
- • Use a slow-downer app to practice at 50%, 75%, then full speed
- • This solo is a masterclass in composition - every note has purpose
Practice Exercises
Scale and technique exercises in the key of F# minor (intro riff) / A major (verse and chorus). Practice these patterns to build the skills needed for this song.
Intro Riff
0:00-0:22Alternate Picking Exercise
One of the most recognizable guitar riffs in heavy metal history - the driving F#-based riff with its signature tritone interval that launches the song with pure adrenaline
Alternate Picking Exercise
- • Palm-muted alternate picking at 138 BPM on the low E string
- • The tritone interval (F# to C) creates the riff's signature menacing sound
- • Galloping rhythm pattern gives the riff its driving momentum
Verse
0:22-1:04Alternate Picking Exercise
The song shifts to A major for the verse, with palm-muted power chord rhythm supporting Ozzy's vocal melody with a more open, melodic feel
Alternate Picking Exercise
- • Shift from F# minor riff to A major power chords
- • Palm-muted chugging between chord accents
- • Power chords should ring on accent beats, muted between
Chorus
1:04-1:30Alternate Picking Exercise
The explosive the signature chorus with full power chord strumming and maximum energy
Alternate Picking Exercise
- • Full, open power chords with less palm muting than verse
- • Maximum strumming intensity for the anthemic chorus
- • Quick D to A transition at the end needs to be clean
Guitar Solo
2:27-3:27Minor Pentatonic Scale Exercise
Randy Rhoads's legendary guitar solo combining classical technique with rock intensity - featuring sequenced runs, sweep arpeggios, precise bending, and his signature wide vibrato over a cycling chord progression
Minor Pentatonic Scale Exercise
- • Solo positions span from 12th to 17th fret primarily
- • Sequenced scale runs in groups of four notes are the foundation
- • Wide, controlled vibrato on sustained notes is Randy's signature

Effects
Distortion:
MXR Distortion+ (Randy's primary overdrive pedal, pushing the Marshall into heavy saturation)
Reverb:
Light spring reverb from the amp

Learning Path
Time Estimate: 3-5 weeks with regular practice
- • Master A5, E5, D5, and F#5 power chord shapes
- • Practice basic alternate picking on single strings at slow tempo
- • Learn the verse chord progression: A - E - F#m - D with simple strumming
- • Work on palm muting technique with power chords
Time Estimate: 6-10 weeks for solid rhythm performance
- • Practice the intro riff pattern slowly at 70-80 BPM
- • Build alternate picking speed incrementally toward 138 BPM
- • Master the palm muting dynamics for verse and chorus contrast
- • Learn the tritone interval and its placement in the riff
- • Play through the complete song structure with transitions
Time Estimate: 3-6 months for complete mastery including solo
- • Achieve clean intro riff execution at full 138 BPM
- • Break the guitar solo into individual phrases and learn each
- • Develop wide vibrato technique for sustained solo notes
- • Practice sequenced scale runs and arpeggio patterns
- • Perform the complete song with both rhythm and lead parts
Practice Notes
Common Mistakes
- • Trying to play the intro riff at full speed before mastering it slowly
- • Inconsistent palm muting - too heavy kills the tone, too light loses definition
- • Sloppy alternate picking with uneven downstroke/upstroke volume
- • Neglecting the tritone interval accuracy in the intro riff
- • Tensing up the picking hand when increasing speed
Practice Routine
- • Warm up with alternate picking exercises on open strings for 5 minutes
- • Practice the intro riff at 70% speed with a metronome for 10 minutes
- • Work on power chord transitions: A-E-F#m-D at full tempo (5 minutes)
- • Palm muting dynamics drill: alternate between muted and open power chords (5 minutes)
- • Solo phrase work: isolate one 4-bar solo phrase per session (10 minutes)
- • Full song play-through at current comfortable tempo
Focus Areas
- • Alternate picking speed and consistency
- • Palm muting control and dynamics
- • Tritone interval accuracy in the intro riff
- • Power chord transitions at 138 BPM
- • Vibrato control for solo passages
Metronome Work
- • Start the intro riff at 70 BPM and increase by 5 BPM per session
- • Practice verse power chords at 100 BPM, building to 138 BPM
- • Alternate picking single-string exercises: 80 BPM to 160 BPM progressively
- • Solo phrases at 50% speed with metronome, gradually approaching full tempo
