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.
