Repetition (phrasing) - Discussed, Part 2

There are two elements in blues songwriting... the HOOK and HEAD... both of which have one element at their core... a cool lick.

A cool lick that goes to the bottom (the rhythm section) is turned into a HOOK by repeating and sequencing (transposing to match chord change) throughout the twelve-bar progression, and continuing throughout the entire song. So, in this case, the lick BECOMES the groove. "I'm Ready" and "Tramp" are great examples of this and "I Ain't Superstitious" is a good example of a modified version of this.

Tomorrow we'll dig into the Head.
