Chord Substitutions: Cooler Chords Part 1
Share this:

My private students often ask me why certain chords work together.  The question is a GREAT question and leads any thoughtful musician down some very interesting roads.  There is a very simple reason why certain chords work together, but the answer to this question also illuminates ALTERNATIVE chords that we can use.  That’s really the topic this article (and YouTube video explores).

Why Chords Work or Don’t

Chords are made from notes – typically a triad.  A triad implies a scale and a competent musician benefits from know their scales, just as a competent writer benefits from know the alphabet.  A triad implies a scale because a triad always represents the same exact thing.  A triad is the Root, 3rd and 5th… of what, you ask?  Of a scale!  So, you can’t have a triad without a scale.  One implies the other.

Another way of putting this is that a chord IS a triad and since a triad IS the Root, 3rd and 5th of a scale then we must get our hands on that scale to start really making sense of the chord.  For example, a D major chord is made up of the Root, 3rd and 5th of a D major scale.  Its that simple.  In the key of D major, we’d call a D major chord a I (roman numeral one) chord.  It means that if we build a triad from the Root (or first degree) of the scale, we get a D major triad – D, F# A.

When we build a chord progression out of chords that ALL contain notes from the same key, we’ll find that the chords “work” together.  If we build some of the chords from notes that aren’t in the key, then they won’t work.

What Are Alternative Chords?

Alternative chords are chords that are still made from notes in the key, but they are built relative to different roots.  A moment ago I explained that a D major chord is a I (roman numeral one) chord because it is built from the 1st note of the scale (a.k.a. the Root).  But, we can build ii (roman numeral two) chords or vii (roman numeral seven) chords.  When we do, the chords will still “work” together, but they’ll be quite different to what you’re used to.  Check out this video explaining a basic chord substitution example in the key of D major:
