Guitar Fretboard Reference
Explore the five moveable chord shapes and their associated scale patterns, pentatonic boxes, and arpeggios. Select a key to see how each shape maps across the fretboard.
Open – fret 4
Based on the open C chord. Root on the 5th (A) string. The shape extends below the root with a wide stretch. As a barre chord, it requires reaching back toward the nut.
Tip: Focus on the upper 4 strings for a practical partial barre version of this shape.
