Miscellaneous
This section contains diadic "fifth" (2 note 'chords'),
the "Sus" chords, and the #11. A #11 contains a perfect fifth
as well as a sharp eleven, (which is the same note as a flat five but an octave
higher).
These chords do not have a Major or Minor tonality, since there is no 3rd.
However the #11 chord does have a Lydian sound.
