Strum the G Chord Scale in 7ths
Descend as well.
Once a 7th chord, the vii chord becomes a very useful chord. Depending on the voicing, it can be used in place of [substituted for] the V7 chord.
The fingering we provided [tab and grids] isn’t the best – it sounds eerily like some type D7 chord.
The most common fingering of the viim7b5 is x-9-10-9-10-x [fingered 1-3-2-4] – it’s the voicing for this chord in the C system at the nut, where we’ve done some work. When we use this fingering, it substitutes well for the Dominant 7. In this instance, it will sound as a V9 without a root.
Strumming chord scales is the ‘academic’ angle. At the start of mapping keys, keep triads and 7ths chord scales as separate exercises. Play them in order. For the jamming part, strum it all…triads & 7ths mixed. We can also endlessly tone toggle any of these chords. In fact, playing the 7ths, as in this lesson, is already a tone toggle, a swap, a change, a mod.
For fixed position chord scales, we now have C and G mapped triadically and in 7ths, at the nut.
