Triads are one of the first harmonic tools to study. They are very useful for comping and chordal enrichment. Learning close and open triad voicings increase your harmonic knowledge and at the same time help you discover your fretboard. In this lesson you will see the main triad chord shapes including root positions and inversions. You will also find some ideas on how to use triads over a II V I sequence, in order to create interesting melodic movement in your comping.

Jazz musicians, composers and arrangers used them as substitutions for diatonic chords for adding more dissonance and spice up the harmony.
This guitar lesson provides 25 altered guitar chord shapes to understand how they are constructed and how to play them on guitar.
Mastering triads on the guitar is necessary for any guitarist who wants to expand his fretboard and theory knowledge.
These chords are not really considered as jazz chords because of their basic sound, but they can be efficient tools for comping and chord soloing. Indeed, the strong point of these chords is the simplicity of learning and playing.
You will find in this guitar lesson 84 ways of playing major, minor, diminished, augmented triads using root and inverted voicings in close and open positions.
