We first played the G Major scale in this session].
We’ve moved the whole shape up one fret. What were opens are now 1 frets.
The A♭ scale is in a fixed position in P1 [fingers can match the fret numbers], unless we use the 3 tones per string. If 3 tones per string, we shift to P2 on the 2 string.
As with any closed system, when we move it, it maintains its quality; its musical meaning. In this instance, all of the scale components are in the same relative position.
12 for 1 = movable to every position → 12 Major scales.
When we move this shape to these positions…the key is…
Notice that most of the enharmonic keys for the Majors, have flat names.
The only key with 2 names in this list, is F# (also G♭ – 6 ♯s/6 ♭s). See the Circle of 5ths. And, D♭ is C♯ (7 ♯s) & B is C♭ (7 ♭s). Yet, we rarely, if ever, see D♭ & B written as C♯ & C♭. D♭ has 5 ♭s (better than 7 ♯s), and B has 5 ♯s (better than 7 ♭s).
64 = 6/4 = string the root is located/finger that starts the pattern. For the key of G Major [the scale form, the heel], we can play this scale as a 6/3, since we don’t have to fret the nut [the open strings]. And, we can start the higher versions with a 3 finger (on the Major root).
And, this Major scale pattern lines up with frame 1 of the pentatonic system & the G CAGED form. If we took out the 4 & 7 tones (4 & 7 to the Major are the 2 & 6 to the minor), we would have frame one of the pentatonic system.
