This question is somewhat abstract, but I’m wondering if this statement is true: “Crosspicking is the most general-purpose [and powerful] picking motion, and it goes full-range. DWPS is really the top half of the crosspicking range, and UWPS is really the bottom half of the crosspicking range.”
In other words, DWPS and UWPS are truncated versions of crosspicking, where the arc of movement is just deeper under the strings.
Thoughts? I’m starting to think that this is likely true, but I’m not sure.
