Ok. Sorry I'll clear that up a bit. When I talking about adding a "seventh", I mean you just count up 7 letters "notes" and that's your "seventh". So you wanted to play a C major 7 chord, the "letter" note would be B. So what I'm referring to is counting. The definition of 7's depends on they way they are altered, but a 7th of a chord is still 7 letters up from root. Take C dominant 7, it would be Bb. It's still B, you just add the alteration (b). In a dominant 7 chord the 7 is flattened once. So B becomes Bb. It's not A# because that is only 6 letters up from C. It's just the correct way to saying chords.
