How to use these chords

I, IV and V (G, C, D) are the primary chords. Together they contain all seven notes of the scale.
vi (Em) and iii (Bm) each share two notes with I, and ii (Am) shares two notes with IV, so these minor chords often stand in for them.
V7 (D7) contains the leading tone, F♯, which pulls up to the root, so it resolves strongly to I. vii° (F♯dim) has the same upper three notes as V7 and is mostly used as a passing chord.
Common progressions, in Roman numerals: I V vi IV (G, D, Em, C); I vi IV V (G, Em, C, D); ii V I (Am, D, G); ii7 V7 Imaj7 (Am7, D7, Gmaj7).
