Yester-day, I ran across my note about the similarity between "All My Loving" and Buddy Holly's "That'll Be the Day," which
I wrote about last month. Just seeing the title of the Beatles' song made me realize that most instances of the phrase "all my lovin'" are sung to notes of all different pitches, providing a sense of this breadth or entirety. In the last line of each verse ("And I'll send all my lovin' to you"), it's sung to the notes C# B A G#, and in the lines "All my lovin' I will send to you / All my lovin', darling, I'll be true," it's sung to the notes E D# C# G# (both times).
