If you’d like to learn the chords & strumming (for sing-along purposes) I have another tutorial for that, which you’ll find here: https://www.youtube.com/watch?v=9Wr6Iy9iNls
In this lesson, I take you through the arrangement, from start-to-finish, working out all the fingerings and making sure you know exactly how to practice this in order to actually get it. I recommend working on the toughest measures first, and then the transitions between those measures. Then work on putting the whole piece together, section-by-section. Use the TAB (link above) to keep track of where you are in the song and this should be no problem!
I hope you enjoy the lesson and have a wonderful holiday season!
