EXAMPLE2 dominant 7th bluesy double-stops based on caged system
Here are some jazz-blues double-stop ideas, which are excellent for playing over many dominant 7th chords. These are all in a George Benson style and
given an idea for each of the five CAGED shapes, so that you will always have one to hand. Of course, practise these in various keys and then on a complete blues progressions as well as in other Dominant 7th contexts. I also recommend writing your own for each position.
