Doesn't matter. I have a few melodies (Well, only one has been included in a song thus far) going in a major scale in my songs, though not in the one I'm doing according to Joonas' instructions. Tends to sound awesome when you have a melody first in, say E major, and then after a while you switch it into E minor. It only works for some melodies though, as the chords get fucked up quite often. I don't want any X minor b5 chords in there. Too dissonant for heavy distortion (Although there's plenty of them in my most recent song, so perhaps I'm growing more tolerant of experimenting with strange chords etc. which result in dissonance). Just got the verse riff down in Joonas' vision.
