C6 be bop tuning

[banjo-guy]

I am thinking of ordering a C6 be bop tuned harmonica. I would like to start on the G that is below the lowest note of the standard tuned 12 hole harmonica. I  would call that the G below middle C. What is that note called when speaking harmonica? G? .

Could someone explain how the numbers are arrived at for the different notes. I assume that each octave gets a number from 1-4 . If that is the case would the lowest C on 16 hole be designated C1 and the lowest note of a 12 hole be C2 ?

What do you think of this tuning idea? I would love to get some feedback before I order.
Thanks in advance.

The low note of a standard harmonica is C4--and for a 16 hole, C3.
So G3 is the low note below the lowest note of the standard tuned 12 hole harmonica.
They don't number the first octave on a 16 and 14 hole harmonica--so C4 is the 1 hole blow.
I think this is a fine idea--I do the same thing with C7 bebop.

Thanks Gary. Do you have an opinion on C7 versus C6 ?

Yeah, I like C7 better; in fact, after retuning a number of chromatics to various tunings, it's the one I like the best!
The 6th tuning is cool too; I have tried a variation where the draw chord is also a major 6th, so it's IV6/V6 chromatic.
Brendan Power has recently claimed this tuning as his own, calling it the Power Chromatic--see https://forums.SlideMeister.com/diatonic-discussion/power-bender-4124.0.html
Will Galison uses the C6 tuning but only for certain songs; mostly he sticks with standard tuning.
Bill Barrett uses C7 mostly; at least, that's what I think.

  Why do you like the added Bb instead of the A natural?  I tried it briefly with a Bb.
  My new job has a part in it with a Db6 Th chord in one of the parts but I am thinking more long term and trying to decide how time to devote to a new tuning. Augmented seems a little less intuitive to me. I know that it's just that I have spent a lot of time on the standard tuning and have gotten into the habit of visualizing a piano keyboard as I play.
 I do like having a major chord for all the blow notes.The 7th chord on all the blow notes doesn't feel right somehow but I am sure I would get used to it.

Bb is the first flat (key of F).
So the key of Bb can be played with only one press of the button (the Eb).
Also, the key of B can be played with only one release of the button (the E).
The chord of C7 and G9 (no root) provide a nice bed for the blues in G.
