The blues scale for guitar is basically just the same as the minor pentatonic scale, with an added “blues note”.  This makes the scale hexatonic, or having six notes.  The sound is as it would seem from the name; bluesy.

Red= Held note Blue= Start of new octave 1-4 = fret The scale should be read left to right, and bottom to top This is the basic outline of the scale.  The fingering can be transposed up the neck on any set of frets.
