Whenever you see that the chords of a song are
made up of 7ths, like in the picture below, you can use the blues scale. There
are quite a few players out there that are playing the blues scale in all kinds
of music. There are more notes in the blues scale to play around with, and it
will give your playing a more sophisticated sound than if you are always using
the pentatonic scales.
Compare this
"A"blues pattern here with the "A"minor" pentatonic pattern below...look at the
way the notes are laid out...you'll see that there is just one note added...it
is known as the "blue" note...if you use these methods of comparison, and study
the different scales, you'll see that they're all just alike, the patterns are
all the same...they just start in different places on the
fretboard.
Just remember to put the root note in its proper place, and play
around with the patterns
