Stance with shorter clubs

I am a beginning golfer with problems with my tempo. But that is not what
this post is about.

I have been studying the book Ben Hogan's Five Lessons and find it very
helpful. There is one thing I cannot find in the book.

He talks mostly about the driver. He does tell you where to place your
feet for the different clubs. But how does your stance supposed to change
when you go from say a driver to a pitching wedge. I mean the vertical
component of the stance.

Do you squat down lower, or bend more at the waist?

i dont think you would want to squat lower, just bend over more at the waist, just be sure not to bend over from the upper upper body

Well Flex your knees, stick your arse out and thats pretty much it. For the shorter clubs means you will tilt a little more.
