Applying Jazz Theory in a Rock Setting

[LiquidMidnight]

Also, how does a rock 12-bar blues or 16-bar blues differentiate from a jazz 12 or 16 bar blues? If I think of anything else, I'll make sure to post it.

Generally, the "skeleton" of Jazz Blues is based on the same I, IV, V progression that is found in traditional Blues. Jazz composers usually embellish the original harmony with chord subsitutions. Often times these subsitutions will resolve into harmonies that are further away from the diatonic key center of the original harmony. (The classic descending II7 - V progression, for example)

If you were to check out some early roots music from the beginning of the 20th century, it really sheds light on how music evolved. You can hear how Blues, Rock, Jazz, Gospel, Country, ect. came from that early music.
