Applications for Alan's "Modular Chord Harmonica"

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!

Applications for Alan's "Modular Chord Harmonica"

Post by IaNerd » Fri Nov 02, 2018 7:14 pm

I am very excited about this: viewtopic.php?f=9&t=267

Around the idea of Alan's modular platform, I have devised some chordal Big Sixes which, in combination with some kind of melodic (e.g. blues scale) Big Six, would constitute a highly adaptable system.

The diagrams below show five different chordal Big Sixes. I also show five tables, each of which describes how these harps can be combined with melodic Big Sixes in corresponding keys.

Some good candidates for the "melodic Big Six" (discussed above) can be seen here:

Here is an alternative note pattern for each layer of the chordal harps above:

Hole 1: lower b7th
Hole 2: tonic
Hole 3: perfect fifth
Hole 4: upper b7th
Hole 5: octave of tonic
Hole 6: octave of perfect fifth

This pattern omits the thirds, and is therefore useful in both major and minor contexts. It also permits three nice octave spits per layer.

The table below incorporates the "alternative note pattern" described in the post just above this one.

It also specifies the lowest possible tunings for Big Sixes, according to Seydel's Configurator at this time. Of course, if one used these six chambers as merely the beginning of a 10-, 12- or 13-hole harp, even lower chords are possible.

Note how every note has an octave-split partner.

If one were to add another chordal harp to this lineup, a good candidate would be a Bb/C harp. Then one could play I--IV--V songs as F--Bb--C.
