“My One And Only Love” was originally composed by Guy Warren in 1947 with lyrics by Jack Lawrence. The tune was not at first a hit, but when Robert Mellin wrote a second set of lyrics for the chart it took notice. Frank Sinatra went on to record it in 1953 and many others followed. It has become a popular ballad amongst jazz musicians and is called often. My One And Only Love has many alternate changes as many notable musicians have recorded it differently. The chord charts below display some of them. The A section includes a series of alternate slash chords that have been made popular by the Real Book. It might be good to know these as well seeing as many younger generation musicians have been using this as a resource.
This tune is most commonly called in the key of C major by instrumentalists.
