Blues is a musical art form I feel that lead the way for understanding
Jazz.
The blues progression is very simple but so many still have a hard time playing
it. The hard part to learn in a blues progression is how to play the
turnaround chords with the right amount of time value for each bar to bring the blues progression back to the top. This then is a correct
blues progression that can be played over and over again.
There are blues guitar type songs that are played on one chord. This is called
more of a static chord vamp to create lyrics sung on top of the one
chord vamp. Licks in one key centre then start to flow an lay musical phrases over the vamp.
The other blues guitar chord progressions are the 8 bar blues, 12 bar blues, and the 16 bar blues. The correct turnaround chords have to be played in the correct tempo of the song without speeding up or slowing down
during the turnaround bars. If you can get through these blues chord
progressions without getting lost during the turn around chords you are
on your way of becoming a great blues guitarist.
Blues guitar is an art form that is very healing and I call it testifying.
The blues guitar in its early folk blues days paid great attention towards the consistent chord vamp or a blues progression. In early times the use of a 3, 4, or 6 note riff repeated at a certain time in the chord progression gave the blues progression song a feeling that you are being rocked in a cradle like a baby child.
