It has debunked the notion that 2wps is superior to a system like Yngwie’s.
Prior to CTC I was of the belief that the pick should be perpendicular and that 2wps was something to aspire to, that it was the best way to play a variety of material. I think I got the notion from “Speed Mechanics for Lead Guitar” over 25 years ago.
When you look at a dwps system like Yngwie’s and his body of work, you realize that he has the best developed system. The “rules” or “restrictions” allow him to play more musical passages like ascending and descending fours.
We can hold up 2wps as an ideal, but there are many things that can’t be played with it because of the “symmetrical” organization of notes that it entails.
CTC made me realize, that what I’ve been doing is crosspicking, and that where I have failed is when I try to use it for real velocity without 2wps. My current playing is a combination of crosspicking, legato, and speed runs that don’t require any pickslant changes.
At this point, I realize that many of my fingerings, things I’ve practiced with the left hand are probably easier to achieve with Yngwie’s system, and I’m fine with that. For instance, I’ve spent a ton of time practicing sequences of fours, with (essentially) crosspicking. To take them to the next level of speed would require an otherworldly 2wps technique, or just conceding that the best way to play them is with some legato and economy picking mixed in.
I think Yngwie’s system is an example of “music first”; he hears the notes that he wants to play and developed an incongruous system to allow him to do that. Systems like Gilbert’s and MABs seem to be more about making music with patterns that have a dexterous advantage. IOW, technique in the name of speed was the primary consideration.
