I’m assuming you’re talking about the fretting hand pinky?
Mine is all over the place and often curled inwards, but as my hand moves it’s moving as well. My uncle used to give me sh*t for not following the 1-finger-per-fret “rule”, like if you’re playing something on the first 4 frets, your index should be the first fret, 2nd fret would be your middle, 3rd ring and 4th pinky, which I ended up adapting more when I started doing the Petrucci metronome exercises, but when I’m just noodling around that thing is like “Don’t forget I’m here too, I wanna play!”
