Here we restate and complement our OO schemes as follows:

Octave-of-Following (OOF)

*E-string-1 at Fret-0 is an E-note with OOF state re E-string-6
E-string-1 at Fret-7 is a B-note with OOF state re B-string-2
B-string-2 at Fret-8 is a G-note with OOF state re G-string-3
G-string-3 at Fret-7 is a D-note with OOF state re D-string-4
D-string-4 at Fret-7 is an A-note with OOF state re A-string-5
A-string-5 at Fret-7 is an E-note with OOF state re E-string-6
*E-string-6 at Fret-0 is an E-note with OOP state re E-string-1

Octave-of-Preceding (OOP)

*E-string-6 at Fret-0 is an E-note with OOP state re E-string-1
E-string-6 at Fret-5 is an A-note with OOP state re A-string-5
A-string-5 at Fret-5 is a D-note with OOP state re D-string-4
D-string-4 at Fret-5 is a G-note with OOP state re G-string-3
G-string-3 at Fret-4 is a B-note with OOP state re B-string-2
B-string-2 at Fret-5 is an E-note with OOP state re E-string-1
*E-string-1 at Fret-0 is an E-note with OOF state re E-string-6

*Fret-0 means the string is open — no fret is fingered. These additions make explicit that strings 1 and 6 are tuned to the same note — an E — one octave apart.

And there you have it. It’s time to consolidate the cognitive handhold on the fretboard that we’ve gained so far — coming next.
