Blues guitar licks are a crucial aspect of any aspiring blues guitarist’s repertoire. Learning chords, scales, and popular blues tunes is obviously important, but if you want to be a master improviser, eventually you’ll need to commit several blues licks to memory so that you can use them in a variety of situations and in a number of keys.
The easiest solution is to use some pre-organized books and video lessons that teach you blues guitar licks. This way, the hard work has already been done for you. Most of these books and videos have organized the licks according to key or chord progressions, so it’s easy to find licks that you can use in a variety of different scenarios.
When you learn a new lick, practice it in several different keys and even transpose licks from dominant to major, minor to dominant, etc. That way, you can get more mileage out of the licks you already know.
