And even in Spain itself you have three romances plus some alien language: Galician (closer to Portuguese), Catalan (French-Occitan family), Spanish (and Andalusia has it's own subdialect), plus Basque.

A Basque playing the txalaparta would look like a guy who came from a UFO for an Andalusian guy playing Flamenco with a guitar.

Ditto with a Galician with an Atlantic culture (and Celtic customs) plus a obvious bind to Portugal because 500 years ago they were the same language against a Valencian living in the sunny Mediterranean towns.
