  "description": "Source-positive Chiapanecan marimba, an existing Central American instrument type with regional identity stated by its performers. Retains three separate original controls: regional form, ensemble practice and bar/resonator construction. No fixed Guatemalan display identity or automatic son-istmeño genre assertion. Grande/tenor and hormigo box-resonator construction are explicitly authored, not measured source hardware. No shared owner or merger modification.",
