General
– another Type of Chromatic Chord Substitution is using “Altered Chords”
– an Altered Chord is a Chord that has One or more of its Pitches Replaced with a Chromatic Pitch, Not Normally Found in the Key
– it is Not the same as Borrowed Chords because it Does Not Belong to the Parallel Key
– the Most Common Altered Type is the Secondary Dominant and will typically be preceded by a Chord that has 1 or 2 Notes in Common & it will always be Followed by the Chord of which it is the Dominant
– this lets you Make a Chord that is the “New” Tonic for a Brief Period of Time, before Returning to the Original Tonic
– i.e. a “V of iii” will be followed by a iii or a “V of vi” will be Followed by a vi etc.
Examples
– for Example the Diagram below Shows C Major Chords in the 1st Line, the 2nd Line Shows Perfect 5ths Higher of the 1st Line, the 3rd Line Shows Dominant 7 Chords of the 2nd Line
– below the V Chord is the V/V and this D Major is Not in the C Major Scale and by Altering that F to an F Flat we have Altered that Chord
Example Altered Chord V/V
Example Altered Chord V of ii
