In summing up (ha!), phase is not just a potential problem in audio engineering. It’s actually one of the essential components of sound alteration. We’ve only touched on some of the most basic theory and techniques here. It will serve a budding engineer well to dive even deeper.
This is an alternate picking exercise that I used to build speed early on in my career. It’s incredibly effective, and you can employ the concept in your soloing. It’s called “modal alternate picking.”
