Based around simple chord progressions and the blending of major and minor tonalities the blues form the roots of most rock and pop styles.

Utilising the pentatonic scale as a start point for improvisation, 12 bar blues chord progressions provide a grounding in simple and expressive soloing. Micro tonal bends and an emphasis on feel and phrasing elevate the style to a supreme art form and it can be the playing of legends like B.B King and Stevie Ray Vaughan which proves hardest to replicate convincingly.
