Song Structure
Understanding B major:
B major has a bright, uplifting character typical of major keys. The Ionian (Major) 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.

Chord Progressions
Main Progression
Classic I-IV-V power chord progression forming the backbone of the song
Theory Insight:
The I-IV-V progression is the foundation of rock, blues, and countless other genres. The I chord (tonic) establishes home, IV (subdominant) creates movement, and V (dominant) builds tension that resolves back to I.
Chord Shapes Used:
B5
E5
F#5
Harmonic Functions:
- B5 (I):Establishes strong tonic center in B major
- E5 (IV):Provides subdominant movement and harmonic contrast
- F#5 (V):Creates dominant tension that resolves back to B5
