  "description": "Azorean viola da terra, distinct from Brazilian viola caipira and mainland Portuguese regional guitars. The museum documents a twelve-wire-string Micaelense model with three double and two triple courses. That construction is an authored representative option, not a measured description of Rafael Carvalho’s 2019 instrument. Wood species, tuning and exact performer technique remain unspecified; axes are authored sonic routing.",
