Parranda
A parranda (English: party or spree) is a Puerto Rican music tradition that takes place in Puerto Rico during the Christmas holiday season. Parrandas are social events that feature traditional Puerto Rican music, food, and drinks. They are associated with pride for the customs of the traditional Puerto Rican jíbaro. The traditional events have been likened to Christmas caroling, but the contents of the songs are secular rather than religious. They are sometimes carried out in the evening, but most traditionally occur in the night, even into the wee hours of the morning. The songs sung are almost exclusively  aguinaldos. Planning and purpose. Parrandas are often spontaneous events and traditionally occur anytime from the late evening to the wee hours of the morning, visiting targeted extended family members or friends in their homes and intentionally waking them up to the parranda music. They reportedly generate a sense of Puerto Ricanness, unity and camaraderie among both those bringing the music as well as the targeted families receiving it. Those participating, whether playing an instrument or singing, are called "parranderos". Instruments used in addition to the voice include the culturally significant instruments of Cuatro, maracas, guiro, palitos, tambora, panderata, panderos (requinto , seguidor and tumbador), trumpet, tambora, and the guitar. Parranda "plot" and venues. One form how the event occurs is most traditionally as follows: A group of friends of the homeowner, musical instruments in hand, arrives at their target house sometime after 10 PM and then, quietly, make their way to the porch or as close to it as possible. The parranda leader (generally, their musical director) signals everyone to start playing their instruments and singing. The music and singing surprises the sleeping dwellers who get up, turns on the inside and outside lights and invites the "parranderos" into the house . Once in, they are treated to refreshments (most homes will be well-stocked with refreshments and Christmas-time traditional foods), and everyone eats and may also dance as parranderos take turns eating and playing the music. The party will go on for about an hour or two, after which, the residents will join the parranderos, with their own instruments if they have then, and move on to the next target residence. As the group grows, the group makes sure to leave for last those homes in which they guess there will be the most food available to support the growing  group or, they simply head to the home of one of the parranderos which has already pre-arranged serving the last meal of the night - the traditional "asopao de pollo", a Puerto Rican chicken soup. The party will generally be over around dawn, when everyone then wishes everyone else good-night and head to their respective homes to sleep. Associated terms and events. The term "trulla" or "trulla navideña" is to the group of people that get together to participate in the parranda. It includes singers, musicians, and anyone else that joins the group. The term "asalto navideño" (literally, "Christmas  assault") is used to describe to the surprise visit by the "trulla" group when they descend upon their sleeping friends at their homes to sing Puerto Rican Christmastime songs to them after they have gone to sleep. Parradas oftentimes include a few minutes reciting "bombas", improvised trovador-like musico-poetic compositions by the parranda participants intended to add fun and excitement to the parranda event.
