This seCTion ConTains some greaT blues ChorD fingerings Here you’ll find some chord boxes to study and then a demonstration piece that puts these shapes into practice. Many of the fingerings work well in other styles too, as the blues genre forms the foundation of rock, jazz and soul music. It is worth noting that the best results often come from using chord fragments, and most players rarely play the full five or six-string chord shapes - particularly live, where bass or keyboards will be taking care of certain frequencies and we don’t want to muddy the water. The 7th chords are often used in the blues and these are embellished by various extensions (9th, 11th, 13th). To add yet more colour, these extensions can be altered (b9, #9, #11, b5, #5).
