Blues tuning **with 7ths** for 12-hole 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!

Blues tuning **with 7ths** for 12-hole harp

Post by IaNerd » Tue Sep 19, 2017 4:55 pm

NAME: Not yet sure. Maybe "7th Heaven Blue Dozen"?

BASIC CONCEPT: For blues in G, it sure would be nice to have the full I, IV and V chords, as well as their dom7 variants, as well as at least one full and proper G minor hexatonic "blues" scale. The "standard" Richter diatonic harp lacks many of these properties. The harp below has all of them.

This is a 12-hole variation of my earlier 10-hole version. Please note that this is deliberately a reentrant tuning, and might require a special set of reed plates and comb.

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

LAYOUT/DETAILS:

Notes of the Blues Scale in G: G — A#/Bb — C — C#/Db — D — F — G

I Gmaj yes, with 7th
ii Amin no
iii Bmin no
IV Cmaj yes (x2, one with 7th)
V Dmaj yes, with 7th
vi Emin no
vii F#dim no

I encourage you to look at the tuning above.

Then, to borrow from Rod Serling: "Submitted for your approval ....""

The overall tuning in this Subject can be accomplished using two Seydel Big Sixes mounted on Brendan's Seydel Twin Big-Six Comb (at http://www.brendan-power.com/combs-diatonic.php ).

An arguably better 12-hole blues tuning can be found in a newer topic called "High Octane" blues tuning for 12-hole harp.
