Name That Chord
Found a shape you like and no idea what it’s called? Click the notes you’re fretting and it’ll tell you — along with every other name those notes can go by, and exactly how it worked them out.
Tap the notes you’re fretting. Each number is that note’s distance in semitones above the root, which is marked in red — so tap a different note to hear the chord from there, and tap the red one to take it off.
Click some notes on the fretboard.
