Guitar (7-String) Fretboard Explorer

Tap any note to light it up across the BEADGBE neck.

An interactive note map of the Guitar (7-String)'s neck in BEADGBE: tap notes to light them up on every string and fret, and see the lattice the tuning builds — fourths with the one G–B major third.

Use it to watch shapes cross the G–B major third: everything that crosses that pair picks up one fret, which is the single irregularity the whole shape system is built around.
