Hey GMC! If you have some skills in theory, probably you have read something about the II-V-I progression before. If you haven't, this lesson can be a good introduction to this topic. This progression is really important to know. As usual, check the video #2 to read and listen some theory.
I hope that also beginners can benefit from this lesson, since the licks shown here are quite easy to play.
Most important, I hope you can find your way to play something jazzy, using some basic concepts which you find here.
Enjoy!
