Fretboard Explorer — Guitar
Tap any note to light it up across the EADGBE fretboard.
An interactive map of this seat's fretboard in EADGBE: tap a note and it lights everywhere it occurs, so the 6 strings stop being 6 separate things to memorise.
Use it to find the same root in three places, to see why a shape you know in E is the same shape five frets along in A, or to find where a bend has to start to land on the note you want.
