FretNinja
A chord is not a shape
Type any chord and see every playable way to finger it across the whole neck.
The ghost map
Every place a chord's tones appear across fifteen frets, glowing at once, with one voicing lit on top. Move through the shapes and the lit grip travels while the map stays still.
Only shapes you can play
FretNinja generates every possibility then rejects the ones that span too far, need a fifth finger, or clash in the bass. What is left is what you would actually play.
Voice leading
Enter a progression and FretNinja picks the shapes that move least between chords.
