Diminished Chord Theory Bands

Diminished Chord Bands

In previous lessons we learned how to play a diminished chord. What defines a diminished, is a minor chord with a flatted fifth. Diminished chords are probably my favorite kind to play because they all carry a special link. The way they are set up creates these diminished bands. When you add a 7th to a diminished chord, you get four equidistant notes. If you play any three of the four notes, you will get a diminished chord of the same caliber. There are only four combinations, so there’s four chords to a band. There are twelve musical tones, so with a little math, we get three bands of four chords in total.

What does this mean?
 
Whenever you play a diminished chord, you can play every other chord or note within its band. Since all four chords within a band share the exact same notes, you can invert them in any way you want. This allows you to play a chord that has a slightly different feel while still remaining within the same key.
 
For example, if you are in the key of D minor, E diminished is in the scale. Instead of playing the E diminished, you can play G diminished or any other chord within it’s band to achieve a slightly different tone.
 

Switching bands creates a sinister feel and can be used to change keys dramatically. Play this sound clip below for an example.
