Hey @johnhorneguitar - and I didn’t read the entire other thread, but here is what I do for absolute beginners regarding slant:
I want to start everybody with a relatively neutral slant but I don’t chastise them or try to change them too much if they naturally slant in either direction. Rather than talk about general ‘technique’ I address the issues as they come up in the simple pieces we are doing.
For example, if there is a passage that is one-note-per-string and descending in pitch, and the student has a natural hard DWPS grip as many do, I talk to them about the tip of the pick and the plane of the strings and suggest a neutral or UWPS stance and doing all upstrokes - BUT I say it’s totally fine for them to keep doing it as they are doing it but to acknowledge that they will have to move the pick more to make it happen at any given tempo.
I point out individual movements and we look at trouble spots in any given piece, and I’ll point out specific things about slants and the plane of the strings but rather talk about slanting as a big picture concept I just use the vocabulary of CTC a bit to help problem solve whatever piece we are looking at.
Related: in a lot of my classes we do the picking pattern from House of the rising sun. Through a CTC lense I have a lot more vocabulary to talk about what goes on there, for example, there are sweeps in two directions and a string skip so I have students use SOME rest strokes but acknowledge what movements need to be made to do the string skip and change the sweep direction.
Now, keep in mind I’m extremely careful to use LANGUAGE and WORD CHOICES that are appropriate for the particular group of students. So I might talk about this stuff a little bit with young children but obviously keep it light and tackle things in very small stages. With adult beginners same deal, I don’t get super technical and wordy with the folks that I know A. will get overwhelmed by it and B. don’t really care much either way anyway.
As for picking grip, I actually have a fairly standardized grip and position I teach everybody that I feel like covers a variety of styles and sounds. It’s essentially resting the right hand base of thumb OR palm on the low strings or body of the guitar depending on which strings are being picked, so most of the hand is essentially on a plane higher than the tip of the pick, if that makes sense. (could show pics if curious) This is also a lot easier if the guitar neck is angled up and out semi-classical style which is also something I teach beginners.
I feel like this is a nice ‘neutral’ approach that then can be modified for different styles but also allow for damping strings if they get into lead electric guitar with gain.
All in all, I don’t stress about it all too much and I’m not too much of a stickler because for a beginning students’ first year or two I just want to make sure they’re enjoying themselves and excited to come back to class, then I know if they want to go all in with guitar and technique we can get much more specific.
Hope that helps…
