Songwriting:  In this episode Joe analyzes the song "All of Me" by John Stephens (John Legend) and Toby Gad. This composition is a masterpiece of modern song construction.  The techniques employed offer composers, in all genres of music, a model to emulate in their works. The use of repetition and repetition with variation of melody, harmony and rhythm is textbook, along with the use of overlapping section and shifting tonal colors.
