In a nutshell. The last of the theory beyond the evolutions of American harmony to points beyond. All 12 pitches are generally at play tin these discussions thus a potential for a continuious chromaticism as the music flows by. Wagner did this in the 1870's at a ballad tempo. Coltrane takes to the rocket ship for 'sheets of sound.' Music written or performed at these degrees of theory machinations is perhaps at the farthest other end of our style spectrum of tonality. The gradual obscuring of the aural predictability of the music.

Objective: Simply to understand the theoretical process of how our stepwise scale groupings evolve into our wider, major and minor third interval arpeggios.

Superimposing triads. This half step above the tonic is often simply referred to by its numerical designation. Generally we'll use the sharp (#) when ascending away from the tonic and the flat (b) designation when descending towards our tonic pitch. I also call this pitch a blue note, but I'm probably the only one that does.

In a nutshell. The diminished color just seems to be able to find its way into every knook of the American chromatic. Each of the styles has probably at least one spot where we might hear something of this doubly even or tripley minor stack'o pitches.

Into the wayback to the mid 30's to Charlie Christian and his "Air Mail Special", the bridge of which is but also chromatic ...?

can be something diffcan be lots of unique things to lots of different players. .

In today's music, while it's near impossible to hear any difference in pitches or tunings, the duality of our pitches enables the blue melodic magic weave over stable, closely tuned chord pitches. Just how central this relationship might be is more about one's own art directions but surely lives at the stylistic heart of Americana guitar. The bend-able string / pitch ability over precisely tuned chords is the basis of our guitar arts.
