At first, seventh chords may seem daunting. Do we really need four notes in one chord? Fortunately, they’re not that complicated. Building seventh chords is actually quite easy, and they have the power to create complex blends of emotions to match the lyrical content of your songs. We just stack thirds on top of the chords we already have. The sound of these higher extensions will ultimately help us build a broader emotional pallet.
Let’s take a look.
For all you electronic producers out there, we’ll be using the piano roll in Ableton Live to show you just how easy it is to complexify your chord structures and the world of bittersweet emotion that comes with it.
Major and Minor Seventh Chords
We’re going to start the same way we started building triads: using only the notes of the major scale. Below is an image you should recognize. It’s a major scale with a triad starting on each scale degree. You may remember that we call these triads that only use notes of the major scale diatonic triads.
*If you need a refresher on common intervals like the triad, here’s a handy article or feel free to check out Music Theory for Beginner Pianists, our free course that goes through common scales and progressions step-by-step.
Now, let’s stack an additional third on each of the first two chords of our scale. Remember: we’re only using notes in the scale, so a third above G will be B, and a third above A will be C.
Similar to how we have major and minor thirds, there are also major and minor sevenths. Major sevenths are 11 semitone steps away from the root (or one step down from the octave), while minor sevenths are 10 semitone steps away from the root (or two steps down from the octave).
When you add a major seventh to a major triad, you get a major seventh chord. When you add a minor seventh to a minor triad, you get a minor seventh chord. In this case, we have a IMaj7 (“one major seventh”) chord and a II–7 (“two minor seventh”) chord.

Dominant Seventh Chords
If we keep going up the scale, continuing to stack thirds on top of our triads, we get III–7 and IVMaj7. Then we reach our V chord.
If you stack a third here, you’ll find that this new interval is a minor seventh, 10 semitone steps away from the root. We call a major triad with a minor seventh a dominant chord and label them by simply adding a seven next to their name or numeral.
Dominant seventh chords are about as unstable a chord as you can get. They have a tendency to drag the harmony along.

Continuing on, we find a VI-7 just before getting stuck again.
On closer inspection, we find a minor seventh on top of a diminished triad. This is called a half-diminished seventh chord or a minor seventh chord with a flat fifth. There are two common ways to label this kind of chord: VIIø or VII–7(♭5).
In the course, we won’t get much utility from half-diminished chords. They have a larger role in jazz harmony, but it’s good to know they’re out there, right?
