- Adding notes to chords, beyond 7ths, is called ‘chord extensions’
- Labeling chord extensions can be tricky, because there is no one universal
standard. (See chart below)
- The most common chord extensions are the ‘added 6th’ and the ‘added 9th’
- When including a note that is a 6th above the root of a chord, this is
called an “added 6th”
- Sometimes a 6th is present instead of the 5th of the chord... in this
case it can be called a sub6 (substitute 6th)
- Added 6ths do not refer to inversion position of the chord
- Regardless of the quality of the triad or seventh, the added 6th is usually
a major 6th with the root
- Regardless of the quality of the triad or seventh, the added 9th is usually
a major 9th with the root (unless part of a dominant 7th chord, in which the 9th could
be a minor 9th) , NOTE: The 9th does not have the be notated a 9th above the root.
For example it is often notated as a 2nd above the root.
- There are several different ways to notate chord extensions using Jazz
symbol labeling… review the chart below. The one we will use in quizzes is highlighted
in red.
