About the Major Triad
A major triad is the harmonic core of major-key music: the root, a major third (4 semitones) and a perfect fifth (7). These three tones of G major repeat all over the neck — learning the shapes lets you find G anywhere and build CAGED chord voicings.
Practice tips
Anchor every shape to its root — the gold R markers — and learn the distance to the other tones. The same shape transposes to any root by sliding it along the neck.
Open the interactive trainer and tap every G Major Triad tone across all six strings until the shape is automatic.
