There are many great lyricists to celebrate throughout the history of Broadway: Sondheim for his complexity and deep understanding of character development, Porter for his sparkling wit and his wizardry with internal rhyme, E.Y. Harburg with his subtly subversive whimsy, Ira Gershwin for his sophistication, and of course Dorothy Fields for her bold, realistic characterizations. Still, I have always been partial to Lorenz Hart who could marry all of the above with an ease and smoothness that elevate the song to greatness without drawing attention to itself. In other words, it is natural. A Hart lyric glides, flows and illuminates.
