Welcome to the forum! You will need to be familiar with your harp and playing some tunes like :Mary Had a Little Lamb, O When the Saints, Etc.
I didn’t hear any bending in the intro so you may get away with not having to learn that first.
Next see if your video player is able to slow down the video so it plays slower. You will have to listen to what he is playing, pick it out on your harp and write down what your playing, it will help you remember.
We will help all we can. Be specific with your questions so we can give you a direct answer.
I started really learning harp a few years back to keep my sanity too. Wife is not to sure it has worked. Now I am Harp Crazy! LOL
