Cavaquinho Fretboard Explorer

An interactive note map of the Cavaquinho's neck in DGBD: tap a note to light it on every string and fret, and watch the lattice this tuning builds — DGBD — four strings whose open notes already spell G major, climbing without a single re-entrant step.

Light the open strings first: they already spell G major, and the outer pair — D, an octave apart — fences the whole hand top and bottom. Then light a single pitch and notice how few places it lives — four strings keep the map small enough to actually memorise.
