The dominant 7th in four positions

Music theory, Seventh chords, 15 minutes

V7 as a four-note chord, its three inversions, and the figures for each: what Grade 6 asks you to recognise and figure.

Adding a 7th

Add one more 3rd on top of chord V and you get V7: four notes. In C major, V is G, B, D; the 7th added is the note a 7th above the root.

The 7th is a dissonance against the root, so it wants to move: it resolves by falling a step. That pull, together with the leading note's pull up to the tonic, is why V7 to I is the strongest cadence of all.
