What problem does it solve? Latin is not one style but three incompatible families, and blending them produces arrangements that sound neither Cuban nor Brazilian. This Skill forces the family and sub-style decision first, then applies the clave system, instrument division of labor, and register discipline that make salsa, samba, bossa nova, or reggae arrangements stylistically coherent. ## Core Features & Use Cases - Family separation and sub-style selection: Distinguishes Afro-Cuban, Brazilian, Caribbean, and Latin rock branches, then narrows to son-salsa, mambo, cha cha, songo, samba, bossa, baiao, ska, reggae, and more. - Clave grammar and grid discipline: Decides son vs rumba clave and 2-3 vs 3-2 orientation, assigns the grid-keeping role to bells or kick drum, and defines who plays tumbao, montuno, and cascara. - Transfer table and ARR-SPEC mapping: Marks which Latin devices can move into pop arrangements and which are clave-dependent, then maps every decision to ARR-SPEC fields like groove.feel, arrangement.roster, and form harmony. - Use Case: When arranging a pop track that needs a Latin percussion layer, use this Skill to pick the correct family, decide whether a clave-based device belongs, and write the spec without mixing Brazilian and Afro-Cuban patterns. ## Quick Start Use the mc-style-latin skill to arrange a bossa nova section for my song and fill in the ARR-SPEC groove and roster fields.
