Dylan, who began working on the book in 2010, offers a master class on the art and craft of songwriting. He writes over sixty essays focusing on songs by other artists, spanning from Stephen Foster to Elvis Costello, and in between ranging from Hank Williams to Nina Simone. He analyzes what he calls the trap of easy rhymes, breaks down how the addition of a single syllable can diminish a song, and even explains how bluegrass relates to heavy metal. These essays are written in Dylan’s unique prose. They are mysterious and mercurial, poignant and profound, and often laugh-out-loud funny. And while they are ostensibly about music, they are really meditations and reflections on the human condition.
