BASIC CONCEPT: I think the title of this Topic says it all.
DISCLAIMER/DISCLOSURE:
I already used this octave in another topic called "Twelve-hole slide harp with 2.3 chromatic octaves, 14 different chords and easy diatonic play."
Also, I am quite paranoid that someone, somewhere has already come up with this particular octave, because it seems almost self-evident. Please let me know if this tuning has been done before--I will not be surprised or upset.
WHEN/HOW: September of 2017. I have not yet had one made.
LAYOUT/DETAILS:
This is "like" solo/tonleiter tuning in the sense that this is intended primarily/entirely for single-note play (i.e. zero chords). And it is "like" the PowerChromatic octave in that it uses the same kind of simple draw bends to achieve accidentals.
The example given here is "primarily" a C major version, though it can be played just as easily in the relative A minor. The C major octave is shown in a red dotted line. Observe however that there would be eight different diatonic pathways from the tonic to its octave.
The solid blue line depicts one of many ways to ascend the g minor hexatonic "blues" scale.
So go ahead: Keep a fully chromatic non-sliding ten-holer on your person at all times! For that matter, make it a Big Six (use chambers 4-9) with a fully chromatic octave plus an additional note!
