Watch the Harmony online guitar lesson by Matthieu Brandt from Chord Cookbook
In this section we'll study dominant seventh chords and alterations of chords within a major scale. We can do this to create strong chord progressions using tension and resolution. The V-I chord progression is the strongest one available to us in pop harmony. If the V chord is major, the tension/resolution will be stronger than if the V chord is minor. A dominant seventh chord wants to resolve even more than a regular major chord wants to. We'll also take a look at how we can put the chord on the seventh degree to use.
