The major chords are made up
of scale tones and usually don't contain any notes that aren't in the
major scale of it's root note.
The minor chords all contain
a flatted third (3)
and usually a flatted seventh (7)
note of the scale of the root note of the chord.
The dominant chords all contain
a third and flatted seventh (3 & 7)
note of the scale of the root note of the chord. This interval produces
the interval called the tritone. This interval creates the tension of
a dominant chord and dictates it resolution.
The other group is made
up triads, dim7, and sus chords that didn't seem to fit into the other
Chords with no links are still under construction.
