Interactive guitar and bass fretboard: every note on every fret, scales, pentatonics, chords and alternate tunings. 6, 7 and 8-string guitar, 4, 5 and 6-string bass. Free and online.
Fretboard shows where every note is on the guitar and bass fretboard. Pick an instrument and a tuning — standard, Drop D or your own custom one — and instantly see the note on every fret of every string, with its octave and frequency.
Highlight a scale or a chord on the neck: major, minor, minor and major pentatonic, blues, modes, seventh chords and more. The root is marked separately, and other notes can be hidden to help you memorize the shapes.
Supports 6, 7 and 8-string guitars and 4, 5 and 6-string basses. Open several fretboards at once to compare tunings side by side.
