Over the years I have played HAPPY BIRTHDAY in all kinds of styles and whatever key was needed at the time. I always had a hankering to work it out finger style with a walking bass line. So here it is! It’s one time through so very short- 10 measures in all. HAPPY BIRTHDAY is usually in 3/4 but I like it in 4/4. I just think it swings a little better. I feel this is certainly a good one to get under your belt. It can certainly be useful on the special days of our loved ones.
So below you will find the link to the PDF of the notation and tab as well as the YouTube video.
