This article explains how I began to use more complex and harmonious chords, instead of simple major and minor ones. Actually, when I first started doing this, I had no thought on music theory behind most of those chords, nor their names (though, through time I learned them). I only focused on how they sound, and what tones fit in each chord. I easily got it into my ears, which changes I can make on chords, for them to sound more exotic while not changing their function or nature.
