John Denver wrote “Annie’s Song” in 1974 in 10 minutes as he went up a ski lift. Go figure. Anyway, it became a #1 song on the Billboard Hot 100 and also #1 on the Easy Listening chart.
It’s in 3/4 time and I played Pattern #13 from my Fingerstyle Ukulele Tutorial (link below) throughout the song. There are a lot of chord changes so you might find it quite a bit easier to just strum it instead of fingerpicking, and a nice easy 3/4 strum sounds good on this song.
