Fretboard Note Finder
Map every note on a guitar, bass or ukulele fretboard for any tuning.
Overview
The Fretboard Note Finder prints a complete note map of a fretted instrument for any tuning. Choose a built-in tuning (standard, drop D, DADGAD, open G, bass, ukulele) or enter your own low-to-high note list, set how many frets to show, and pick sharps or flats. It outputs a clean monospace grid with the highest string on top, ideal for learning the neck, planning chord voicings, or transcribing in alternate tunings.
