Today I uploaded a lesson to my YouTube channel on one variation or embellishment, of the typical 12 Bar Blues Progression. Its a progression thats used in Jazz and gives you a few more options when soloing or just writing a melody over it, (I'll be covering the theory I use to solo over it over the next two weeks).
Have a watch see if its useful for you, let me know what you think
