My friend and I are looking to just enjoy ourselves and record a Death Metal EP with some Doom and Melodic Death Metal influences. With the tempo changes I know it sounds ridiculous but at this point it's hard to get my sounds out with words so I hope someone understands that.
Anyway, I know I'm going to play in drop C more than likely, I was just wondering what kind of theory lessons or small facts about how melodic death metal is composed would help me when I can hear it but I don't know how to fret it because it's complex to me.
I know the tempo of the songs are going to be frequently changing (which we want) and I'm not so worried about technique rather than finding some sort of key to play in (and I feel as if I know the answer is that it is up to me), and I know that string skipping and the 'audio illusion' of one sound has to be tonally correct. I am just sort of lost as to where to start building these improvised songs into something sensical.
