I am going to start with the music because well that starts way before and Trinidad has it's own music for Christmas. Parang. Although Trinidad is an English speaking country we celebrate Christmas in Spanish.
Traditional Parang comes in a few categories:
Aguinaldo/Serenal : Parranderos sing the arrival of the season. (Sereno Sereno)
Anunciacion : Sings about the Angel Gabriel giving the good news to the Virgin Mary. (Le Anuncio)
Nacimiento : Sings about the birth of Jesus and the three kings. (El Nacimiento)
Despedida : Parranderos sing the farewells of the season. (Vamos Vamos Vamos)
We sing the traditional carols but along with learning Silent Night we also learn Vamos Vamos Vamos. We don't go caroling we go paranging regardless of what is actually sung, if anything. Paranging is also used to describe just showing up at someone's house during the Christmas season to visit and eat.
