Here's a simple 7-minute tutorial on an arrangement of "Silent Night" if this helps
I was about to become a member of the "Didn't learn a new Christmas Song this Year Club" when I saw your video. I usually start practicing my meager collection of Christmas songs just about a week before Halloween to "re-remember" them and hopefully play them a bit better than the year before. I have several versions of Silent Night by people like Dan Coates and others, but I really didn't like the arrangements. They were either too complex or too simple. Not being able to play "Silent Night" seemed like a glaring omission in my "limited" Christmas repertoire.
Your "simplified" arrangement is excellent! It sounds good just "as is" or like a basic recipe ...you can add to it, or change it slightly to make it your own. I modified it by playing the left-hand chords as for example, a C-G-C stretch instead of C-E-G to give it a "bigger sound" and varied some of the left hand patterns in a couple of measures from 3/4 to 6/8. It is still simple to play and sounds great to me! Thank you so much!
For next Christmas, I'll transpose it from C to Ab for us lower-voiced people! A Db is much more manageable for a bass than that high F!
