          A                   A7                   A7                    A7                   A7
         A9                   A13
In blues, typically major and dominant chords are interchangeable. So, should you ever see a chord chart
with A or A7 then any of the above chords could be used.
                                        Altered Dominant Chords
        A7#5
Altered dominant chords have a very specific purpose and should only be used sparing, usually just before
the chord progression moves to a chord a 4th away. In this case A7#5 should be used just before a chord
progression would move to a D chord. The obvious place to do this would be when playing in the key of D,
then the A chord in bar 12 could be substituted with an A altered domain: A7#5.
                                      Barre Chords – Root 5th String
                                                   Major
          E7                     E7                    E7                  E7                  E7
            E9                  E13                    E9
In blues, typically major and dominant chords are interchangeable. So, should you ever see a chord chart
with E or E7 then any of the above chords could be used.
                                          Altered Dominant Chords
          E Aug                  E7#9                 E dim
In this case, the above E altered dominant chords should be used just before a chord progression would
move to a A chord. The obvious place to do this would be when playing in the key of A, then the final E
chord in bar 12 could be substituted with an E altered dominant.
The Diminished Chord can be found in the song Need Your Love So Bad
                               Dominant 7th Chords – Root 4th String
          A7                       A7                         A7                     A7
As stated earlier, in blues, the above chords are interchangeable.

          E7                     E7                      E7                    E7                   E7
          E7                     E7                     E7
The above chords are all E7 chords which make use of open strings and are interchangeable and an
interesting way of creating original chord based riffs and are particularly well suited to acoustic guitar.
