Cuban Tres Fretboard Explorer

An interactive note map of the Cuban Tres's neck in GCE: tap a note to light it on every course and fret, and watch the lattice this tuning builds — GCE — three courses whose open notes already spell C major, with the G sounding above the C beside it.

Light the open courses first: they already spell C major, which is why so much of the son repertoire sits where it sits. Then light a single pitch and notice how few places it lives — three courses keep the map small enough to actually memorise.
