1. If Eternity Should Fail
Different tuning
Drop DMeasured
Notes
How to get there from the album's E Standard: String 6 down a whole step (E → D); the other strings stay.
Drop D, guitars and bass, the band's first song recorded that way according to Loudwire. Bruce Dickinson wrote it for a planned solo album.
Loudwire reported in 2015 that the song is in Drop D, a first for Iron Maiden; Wikipedia calls it the band's first collective use of the tuning. Bruce Dickinson wrote it for a planned solo album. All three guitar parts of the Songsterr tab are in Drop D, and TuneLit's check from the audio hears the low D.
