Fig. 1: Extended G Major Scale
The root (G) is in parenthesis. It appears 3 times. The G major scale consists of 7 notes: G, A, B, C, D, E, and F#. Number them, in order, from 1-7 and you’ll have your scale steps. The 1st scale step is G. The 2nd is A and so forth.
Fig. 2: G Chord
Here is the G chord played two ways. It’s the 1st, 3rd, and 5th scale steps.
Fig. 3: Gsus2
We get a suspended 2nd chord when we add the 2nd scale step (A) to the G chord triad. Each measure below begins with the Gsus2 but resolves to a plain G chord.
Fig. 4: Gsus4
If we add the 4th scale step (C) we end up with a suspended 4th chord.
Fig. 5: G6
By adding the 6th scale step (E) we create a sixth chord, or G6.
Fig. 6 Gmaj7
When the 7th scale step (F#) added to a G chord gives us a G major 7th (Gmaj7, GM7).
