G Chord Progressions: Basic Triads

If you remember from previous entries, the G major scale consists of the G, A, B, C, D, E, and F# notes. This scale will relate directly to the simple triads (that is, three-note chords made of the root, major/minor third, and diminished/perfect fifth notes) in the key of G major (please refer to this website or elsewhere for more information):

I. G major (made of the G, B, and D notes);
ii. A minor (A, C, and E notes);
iii. B minor (B, D, and F# notes);
IV. C major (C, E, and G notes);
V. D major (D, F#, and A notes);
vi. E minor (E, G, and B notes); and
vii(b5). F# diminished (F#, A, and C notes).

As we'll see later, the capitalization or lack of capitalization for the above Roman numerals provides an additional visual aid when substituting chords in different keys.
