uh... I'm guessing you're pretty new to songwriting because that sounded really random. putting a A# in the bass while you are using completely different notes in the other two guitars doesn't really add anything
Yeah you need to try to work out a couple of things. First, fix the timing. Make sure everything matches up with the other tracks. Second, make sure the notes used are in the same key as the others. you don't wanna have it coming out sounding sour.
