Benny Goodman had his first #1 hit with "Moonglow" in 1934, and many jazz legends have recorded it, notably Billie Holiday, Django Reinhardt, Lionel Hampton and Errol Garner. It was featured in the 1955 hit movie "Picnic," and has had at least 500 recorded covers. Notice, in this key-of-C arrangement, that the A section of the AABA tune has a 6-note phrase that is repeated three times. Many pop songs of the 20s, 30s and 40s have such a brief repeated phrase (think of "All of Me" (three notes), "As Time Goes By" (six notes) and "Autumn Leaves" (four notes). The last two bars of the A section are also a strong "hook" that makes this tune memorable.
