Master the Guitar Neck

This Interactive Guitar Fretboard Visualizer is designed to help guitarists of all levels understand music theory. Unlike static charts, this tool allows you to dynamically switch between keys, scales, and modes including Major, Minor, Pentatonic, and exotic scales. Whether you are a beginner learning the CAGED system or a pro exploring alternate tunings, this engine renders the logic instantly.

The CAGED System

Visualize movable chord shapes across the entire neck. Toggle the View Mode to "Chords (CAGED)" to see how the 5 foundational shapes (C, A, G, E, D) connect to form a comprehensive map of the fretboard. This is essential for unlocking the entire neck.

Alternate Tunings & Capo

Explore the fretboard in Drop D, DADGAD, or Open G. The engine automatically recalculates every note and interval. Use the Capo feature to instantly transpose your visualizer without doing the math in your head.
