Chord Extensions

The most basic chords are triads but when you want to be more expressive and create interesting moods you would look at chord extensions.

The chord extensions below all have their own sounds and can be used for specific moods individually or in combination with other chords.

All chords extensions are made up of a Triad and some notes added. Once you know how to work them out no chord is beyond your understanding and with the help of the guitar fret board or a diagram showing the keyboard notes you will be able to find playable options of each chord.
