C vE G vBb = Cv7 = "C down seven"
C vE G vBb = Cv7 = "C down seven"


All 7th chords follow this same pattern. Likewise, if a 6th is not a P4 or A4 above the 3rd, it's an "add-6" chord. Permitting add-7 chords has the added benefit that the wordy "minor-7 flat-5" can be replaced with the more concise "dim add-7", written Co,7. "Half-dim" can still be used, e.g. C uphalf-dim is C ^Eb Gb ^Bb. But half-dim is problematic because the slash-circle abbreviation for half-dim is hard to type.

Also, in many edos "half-diminished" can refer to lowering by half a sharp.  


In the table below, if a chord is '''bolded''', the comma must be spoken as "add".  
In the table below, if a chord is '''bolded''', the comma must be spoken as "add". In non-bolded names, the comma can be omitted when writing the chord, although that might make the chord name less readable. 
 
''Question: for all tetrads and pentads, should a comma that needn't be spoken as "add" be omitted from the written name?''
