Neck Explorer — Dobro
Tap any note to light it up across the GBDGBD neck.
An interactive map of this chair's neck in GBDGBD: tap a note and it lights everywhere it occurs, so the 6 strings stop being 6 separate strings to memorise.
Use it to find the same root in three places, to see why a shape you know in G is the same shape two frets along in A, or to plan a fill before your hand commits to it.
Every note a groove asks this chair for is somewhere on this board already — the parts engine just names which ones.
