This is the first post in a series where I’ll be looking at how we can develop improvisation techniques over the blues. Melodically I’m going to be looking at how we can build and develop improvisations and harmonically I’m going to be looking at how we can vary the basic blues progression. In the first 12 bars of the video I play only the chords of a basic blues progression in G. The notation and TAB are given below the video. In the second 12 bars I start to add the guide-tones. For a description of guide-tones go to my previous blog post on Guide-Tone Lines. Have a go at playing the guide-tone lines along with the video.
