So yeah when i play with my first 3 fingers my pinky curls up and then i have to bring it back straight when i want to use it, so i can't play as fast. is there any way to keep this from happening?
Pics might help. You'll get it over time, Even the best/fastest had to start out slowly, picking out all the sloppiness
i guess. its been going on for years and its just now starting to piss me off.
Stop rushing things, just slow down
Most people's pinkies are initially less dextrous than other fingers. Practicing very slowly and smoothly, and taking a moment to "pose" correctly over chord shapes helps a lot.
