Practice the 12 bar blues until it becomes second nature to you. Use only the grid we made with the numbers (Roman Numerals) Play it in the keys of C, G, D, A and F (for a gold star). We'll play it some more next week with songs and add some fun licks. If you look around on the internet you will find some small variations on the 12 bar blues (a V instead of a I, less or more 7th chords). It's all the 12 bar blues with slightly different interpretations.
