Goldschmidt/Sowards Gen. 5 Penchromatic tuning for 14-hole slide harp

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!

Goldschmidt/Sowards Gen. 5 Penchromatic tuning for 14-hole slide harp

NAME: “Goldschmidt/Sowards Gen. 5 Penchromatic tuning for 14-hole slide harp”

BASIC CONCEPT:
The Gen. 4 version of “Goldschmidt/Sowards” tuning took a step forward by splitting the Slide In-Draw layer into two sets of notes, such that the right half of the comb’s chords could be in roughly the same register as the left half. This was made possible by having four separate reed plates of six reeds each, i.e. it would utilize the brand new QuadSix Switch Harp technology created by Brendan Power. A significant problem with that overall tuning is that there is a sizeable physical discontinuity in the three “notes” layers. This Gen. 5 version assumes the availability (not yet existent) of a 14-hole slide harp with reentrant tuning only in the Slide-In Draw “chord” layer.

WHEN/HOW: December of 2017. I have not yet had one made.

LAYOUT/DETAILS:
Observe how all the draw notes can be bent by one semitone. This makes playing NEARLY chromatically (and in the minor hexatonic blues scale in G) possible with or without the use of the slider notes.
