Aight LGM JuSe is breaking out the foundation blueprint for us all. I am digging it. I just pulled these out for my students a couple days ago.
Like most of us here, honestly, I like hearing rudiments but I don't like practicing them (especially when they don't sound crispy). However, the Quandrant is a great way to get past that. It takes thes pressure off by giving you a "stairway" type progression so that you can see/feel the improvement as you go.
This is a good way to get back in the swing of things.... especially after watching that Sonny Emory solo, lol, where he builds from the foundamentals up.
