the only problem with all of this is that you must ingest the entirety of the information before becoming unconsciously competent. Do you think skilled guitarists actually think about this while they play? It's a complete flow state; prefrontal activity just shuts it down.

There are different stages of composition in music. By the time you're playing music, you ideally should not think this way.

But it's nice to have a visual way of seeing substitutions that work with your progression as you write music.
