The II-V-I pattern is the most common pattern in jazz music. The more adept you are at playing this pattern in all the keys the better your facility in the jazz language. In the past 20 years I have been keeping a notebook of these patterns. I've tried to limit the ones in this 200 page book to the hippest ones and to strain out the ones that are more popular or overused. In my opinion these are the best II-V-I licks that I've come across in the past 20-25 years. There are 200 licks in this 204 page pdf file.(120 Major Licks and 80 Minor Licks) Each lick is transposed into all 12 keys using Finale and is easy to read.Trust me when I say that these things will keep you busy for a long time but once mastered your playing will improve incredibly.
