This week is Carnival, a holiday in my country! It's a fun festival with a lot of people partying in the streets, with music and dancing.

Galicia is a very traditional (or you can say typical) folk music at this party. (Or you can say...Galicia is a traditional folk music that is played at this festival.

...I see alot of entries for this Carnaval...sounds awesome!!

Good job!
