Watch the Coloring Chords online guitar lesson by Matthieu Brandt from Songwriting on Guitar
Each major or minor chord can be colored by adding notes from the key you are in or even notes outside of this key. The pallette with which you'll be painting your moods will be larger and your compositions more varied. On guitar we arelimited to six note chords max and to chords that have playable shapes. On top of that certain chord shapes might be playable, but just don't dound that good in a solo acoustic guitar setting. You can even introduce chords to your progressions that are not major or minor; think sus2, sus4 chords and power chords. Options galore!
