Another thing worth developing is the ability to improvise with the Blues scale while playing a shuffle with the left hand. First, practice the scale itself over one chord, then use the whole 12 bar progression.
Here the Blues scale is played over the left hand part for a C chord.
This time repeated figures are played over the shuffle pattern.
Here is a 12 bar Blues solo which makes use of these techniques. Notice the use of the G chord instead of C in the first ending. This is common in Blues and is used to set up the next verse.
You now know enough to start improvising your own Blues solos. You can use any of the ideas presented so far as a starting point. The main thing is to experiment and have fun with the music, remembering that the more you do it, the better you get. It also helps to have some kind of a theme in your playing and to develop it through repetition and variation.
