Here’s a quick reference guide to essential guitar chord forms. Every chord is spelled out in notation indicating each note’s position or function within the chord (Root, 3rd, 5th, 7th, etc.). The three most popular forms of each particular chord are shown in three different locations on the guitar fretboard. A diagram of the entire fretboard reveals the location of every tonic or root tone for each chord. 

In addition, handy side tabs help you locate the exact chord form needed in seconds. From each tonic note, the following chords are presented in multiple forms: Major, Minor, Dominant 7th, Diminished, Augmented, Minor Seventh, Sixth, 7#5, 7b5, Major 7th, Major 7b3, Minor 7b5, 7sus4, Minor 6th, 9th, Major 9th, 9#5, 9b5, 7b9, 7#9, 6 add 9, 7#9, 11th, Augmented 11th, 13th, 13 b9, 13 b9 b5. That’s some 324 chords in all. Just imagine what you might do with them!
