Hello there,
Would you consider adding a note about the location of the cadence? You show that most songs cadence on the fourth measure. There is an example in the book mentioning “I don’t want to miss a thing” but THAT example has the cadence on the sixth measure. This may throw others off and maybe a note stating that the cadence CAN be in a location other than the default fourth and seventh measures.
Musically yours,
