Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!
BASIC CONCEPT: A 12-hole slant harp with a "standard" Richter left side, and a right side where every “blues scale” note has at least one unbent draw or blow spot PLUS an enharmonic twin that is a fully-bent draw note.
WHEN/HOW: September of 2017. I have not yet had one made.
LAYOUT AND DETAILS:
Notes of the Blues Scale in G: G — A#/Bb — C — C#/Db — D — F — G
I Gmaj yes (x2), one with 7th
ii Amin no
iii Bmin yes, partial
IV Cmaj yes (x3)
V Dmaj no
vi Emin yes, partial
vii F#dim no
**FUN FACT** There are 192 pathways from the lowest blues scale note up to the highest (or vice versa), and 36,864 pathways up-and-then-down (or vice versa) all the blues scale notes.
Addendum #1: This entire tuning could be bumped up by one octave. The result would be a left half which for many people would be easier to bend, but possibly a right half that is harder to bend.
As a compromise, a tuning like this could be reentrant, as follows.
Raise channels 1-6 by one octave. Change 7 blow to G, but do NOT raise channels 7-12 by an octave. Now we have the same sort of tuning but with a shorter voice and--for some folks--easier to play.
