Interactive Guitar Learning Tool
A comprehensive web app that helps guitarists master the fretboard through interactive visualization, music theory education, and gamified practice modes.
🚀 What is Fretboard Master?
Fretboard Master started as a simple chord transposition tool and evolved into a complete fretboard learning platform. It combines interactive visualization with music theory education to help guitarists understand their instrument at a deeper level.
