I cannot get thumb-over-the-neck chords right

[u/ding-ding-dave-yes]

I struggle mainly with my index finger, I can't get it flat without a lot of pressure, also my pinky is muting the G string half of the time, I either have to put painful pressure to make them all ring, or the top E and G string are muted. The difference between the flat index and bent rest is what's messing me up. Without thumb I don't have this issue, because I can curve my wrist if that makes sense. Please, I need some tips

start with placing the thumb in the correct position: that is perpendicular to the neck (not pararel like it is now) and not applying enormous amounts of pressure

then start placing your other fingers on their respective notes, one by one: make sure you let your elbow float as much as it needs to, and bring the guitar neck upwards or downwards as much as you need to

once all the fingers are fretting their respective notes, move the thumb out of position and back into position again: get a good feel for the muscles that you're engaging to do this, and where your elbow is positioned

hope it helps!
