C Major: C, E, G
...and drop the 3rd down to the 2nd degree of the scale, we get:
C2: C, D, G
This "2 chord" sound is easily recognizable as being prevalent in a lot of FZ's compositions.
If we invert the C2 chord, we get:
C, D, G - D, G, C - G, C, D
It is interesting to me that the second inversion of the 2 chord is stacked 4ths. I'm going to look out for this a little more and find some parallels.
