Re: Chords and what they mean

[BB]

May be I misunderstood ...

c:5 does not have a 3rd and is therefore indifferent - not minor not major and therefore is not really a chord. ( i know it with the nick name "hollow fifths") It is not equal to the c chord but has a special quality with a "hollow" or crypt sound. It is frequently used in metal genre, some metal groups use it exclusively.

c:5+

is in use as
Caug, Eaug/C, G#aug/C

c:5-

is seldom used and is
Cb5

and c:5- then.  Those aren't redundant.
