“Marie,” by Randy Newman is stunningly beautiful and sad. Though I consider it to be easy enough for beginners, you do need to be able to play the chord shapes in the song. I suggest starting with those. Then play just the top note of the TAB as that will be the melody. Then see if you can combine the melody with the chord shapes. Try to master (more or less) just a couple bars at a time. And skip around the tune. You’ll get more bang for your buck by learning it out of order. The reason for this will become clearer in time.
And here is Randy singing it so you know how it goes. I will record it myself and post it when time allows.
