Honestly, there is no one correct way to hold the pick. I’ve been analysing pro player technique for so many years, and I’ve seen so many different guitarists hold the pick in so many different ways. Any you know, I think it’s also quite common for guitarists to change the way they hold the pick depending on what it is they’re playing.
This said, as a starting point, the video above gives you a solid foundation for holding the pick when starting out.
