G Scale Maps — Puerto Rican Cuatro (Standard)
All 24 types over G, drawn where the 10 strings in 5 courses and twelve frets actually put them.
All 24 scale types this site maps, rooted on G and drawn for the Puerto Rican Cuatro (Standard): the majors and minors the repertoire actually moves between, the pentatonic and blues shapes, the modes, and the symmetric and world families.
Every map marks the root wherever it appears, which matters more here than on a wider instrument — inside a minor thirteenth the same pitch class turns up again quickly, and the map is what stops you mistaking a repeat for a new note.
