The reality is, though, that you can do quite a few things creatively using these 3 note chords exclusively.
To demonstrate you what kind of possibilities you would have, I'm in the process of creating a set of variations on the famous Christmas carol "O Come All Ye Faithful" (Adeste Fideles) for organ.
Not only am I using major and minor chords freely to create a quite surprising sounding, modern, and colorful music but I'd like to teach you how to do it also so that you could create something similar on your own hymn tune or melody as well.
