The Chord Ladder | A Unique Way to Understand Chord Progressions

An interesting aspect of chords is their relationship to other chords. This in and of itself produces what we know as chord progressions. But how do these relationships work? All chords have a "harmonic gravity" to them. There's a very simple concept called The chord ladder. This visually demonstrates the direction that chords tend to move.

The top of the ladder represents chord tension with chord resolution on the bottom.  Each step on the ladder may reference one or more chords. When a step has more than one chord, it means that they can substitute for each other.

 

Chord Substitutions

The first step of the chord ladder has the I chord (the tonic). It also has the vi chord. These two chords can be substituted for one another because they share common tones. In respect to the key of C Major, we have the C Major chord (the I) chord and the A minor (vi chord). They both share the tones C and E.The Chord Ladder | A Unique Way to Understand Chord Progressions

The second step of the chord ladder has the V chord and the Vii° (diminished 7th) chord. We have the G Major (the V chord) and the B diminished (the vii chord). The common tones in these chords are B and D.The Chord Ladder | A Unique Way to Understand Chord Progressions

The third step of the chord ladder has the ii chord and the IV chord. We have the D minor (the ii chord) and the F Major (the IV chord). The common tones in these chords are F and A.The Chord Ladder | A Unique Way to Understand Chord Progressions

The fourth step of the chord ladder only has the vi chord. It's A minor (the vi chord).The Chord Ladder | A Unique Way to Understand Chord Progressions

The fifth step of the chord ladder only has the iii chord. It's E minor (the iii chord).The Chord Ladder | A Unique Way to Understand Chord Progressions

The ladder of 5ths

Even though the chord ladder has substitute chords, you'll find that they look very familiar without them. Many chord progressions are circular as in the circle of 5ths. If we look at it without the substitution chords, they're identical to what you will find moving counterclockwise around the circle of 5ths. (The example is in the context of C Major)The Chord Ladder | A Unique Way to Understand Chord ProgressionsThe circular chord progression is the 3-6-2-5-1 progression.

Now listen to the chord progression as it's played with the substitute chords (36471 progression).The Chord Ladder | A Unique Way to Understand Chord ProgressionsThe Chord Ladder | A Unique Way to Understand Chord ProgressionsThe ladder of 5ths chord progression sounds very smooth, but very predictable. Our chord ladder chord progression adds more interest due to the fact it doesn't sound predictable. This takes this listener on a more interesting journey until it comes to a resolution (the I chord).

Typically the V chord leads to the I chord. But with the substitute (the vi chord) on the first step of the ladder, you don't have to resolve to the I chord. You can play the vi chord and keep the progression going.The Chord Ladder | A Unique Way to Understand Chord Progressions

This is known as a deceptive cadence because after hearing the V chord, the ear expects the resolution of the I chord. Instead, the ear is taken on a detour and the resolution is delayed.

The chord ladder isn't a hard and fast rule of chord progressions. It's simply a guide and a visual representation of where chords tend to gravitate. When you're working on chord substitutions and re-harmonizations, simply use it as a starting point and go from there.

Until next time, Go Play!
