Puerto Rican Christmas Traditions Parrandas is Christmas caroling Puerto Rican style.
Friends gather late in the evening to go from one house to the next singing traditional songs.
The parranderos must surprise the unsuspecting friend and wake them with their music. The parranderos gather outside the front door and at a signal the musicians play and the rest sing. At each house they stop for a while and party, then they go to the next house. Often the members of the house join the parranda and it grows in numbers during the evening. Asalto or trulla are other words for parranda.
