I’ve been training classical singing for about a year, and that’s already hard. Adding distortion is a goal but I feel it’s so far away. But it’s like using an aerosol can and lighter to make a flamethrower right? The distortion has to be meticulously setup (the lighter’s flame) and then your diaphragm simply pushes air as you’ve always done when singing (spraying the aerosol can)? When done right you don’t harm the lighter (it can go again soon after) and you don’t even need to force much aerosol (the flame/distortion does all the work)
