Re: music theory help

The 6 does not mean add a major 6. It means the triad is in its first inversion. 6/4 means the triad is in its second inversion.

In every major scale there are 3 Primary chords (I,IV,V) they are capitilized because they represent major triads in the major scale

There are also 3 secondary chords (ii,iii,vi) in every major scale. They are not capitilized because they are representing the minor triads in the major scale

And there is one diminished triad in every major scale represented by vii o. The o represents a diminished triad. Diminished triads have minor 3rds for both intervals. Not used as commonly in today's music


The key of Gmaj will be used for this example, Em is the relative minor for Gmaj

Cmaj = IV in Gmaj scale

G=I
A=ii
B=iii
C=IV
D=V
E=vi
F#dim=viio


IV= C
G
E
C <------ bass note

IV6= C/E
C
G
E<------- Bass note

IV6/4= C/G
E
C
G<-------- Bass note

When using an inverted chord, the only note that truly matters is the bass note to determine what inversion it is in.
