typo? N6 is a short way of writing Neoploitan 6th chords which catsPhiddle brought up. That is a chord built on a flatted 2nd degree of the scale. I studied about them a couple years ago in college and forgot about them untill they were brought up.

If your just trying to be "jocular," you can try using less offensive language. It might also help if you could understand what I said in the first place instead of just telling me my words were irony or a typo.
