OK Paul, firstly the copedent is of my own development, to incorporate most of the popular Hawaiian tuning without having a seven or eight necked guitar.
The Emmons Copedent for my country/Irish playing is the Emmons/Myrick E9 added 6th. BUT I achieve the changes totally "rectum about fizzog".. ..In raise my B's with my RKR - flatten my E's with pedal "C" - Raise my G#'s with pedal "B" ..- LKL is my E's to F change, and so on. Totally unorthodox. When I leaned to play I had absolutely no reference point to work from, only what I could hear and guestimate. Not books Tapes or whatever, just the "Lugs".. been using them ever since..
Oh yes I almost forgot.. The chord name is probably incorrect, BUT what else could you call a chord that has, from the lowest note b9, b5, 7th, 3rd, aug 5th and the root on top ?
OK, like, thumb on fret 6 on strings 5+6... 1st finger fret 5, string 4,... 2nd finger fret 6 string 3... 3rd finger fret 6 string 2.. and 1st finger fret 5 string 1.(1st finger bars strings 1234, but it's modified by 'tother digits..
its an A augmented seventh with a flat fifth and flat ninth. (Maybe.. The easier name would be Eb9b5 BUT that name would be alien to the key pat's using it in. (C) the prior chord is C and the following one of Dm7 so the tonal centre is leading to Dm7, a variance of A dominant 7th is logical.

The Bass is playing an A note and I am playing a Bbm6MA7 with the major 7 as the top note..
How can you have an augmented 7th when the 5 is flat?
Well, the augmented chord works against a whole tone scale or vice versa, so logically any note of the whole tone scale an be a modifier.. perhaps..
