Notice
Start by tuning your low E string down a whole step to D. The opening triads played against the open sixth string should be muted with the edge of the palm of the picking hand and attacked aggressively for maximum percussiveness. This opening is similar to Ratt's "Wanted Man", and this type of rhythm pattern is very common in heavy metal. Curiously enough, the soloing in the fills between the verses is derived from D Mixolydian.
Warren DiMartini's guitar solo begins with sliding arpeggios based on D Mixolydian without the 2nd and 6th degrees intervals. Warren sticks to straight arpeggios in a descending pattern (bar two) before moving into D pentatonic minor (D,F,G,A,C) and D Dorian (D,E,F,G,A,B,C). Over the Bb chord Warren plays Bb Lydian (Bb,C,D,E,F,G,A), which can also be thought of as D Aeolian (D,E,F,G,A,Bb,C). As you may have noticed, this is the same as D Pentatonic minor, with the 2nd and b6th degrees included. Warren's soloing over the fade is based primarily on D pentatonic minor with a repeat appearance of D major triad arpeggios.
