5. Knocking On Heavens Door – Bob Dylan
Although some of Bob Dylan songs require you to “break fingers”, Knocking On Heavens Door is a walk in the park. The 4 chords are enough to play it. The first line of chords is G, D, Am7 and the second one is G, D, C. And that’s it! Just play them in that order and follow the rhythm. Congratulations, you learned the song.
