The Cuatro Project has uncovered a marvelous bouquet of traditional string instruments that flowered all over the island but which, for the most part, have disappeared from public view. At left is an illustration and a list of the flowers in this Puerto Rican bouquet. The variations in each category are sometime regional (where a similar instrument is known in different places by different names) or the instruments themselves are regional (they appear to have thrived only in one distinct region). Some instruments on the list may be apocryphal (we have only some evidence that they existed but no incontrovertible proof). Finally, some of the names are suggested names coined by the Cuatro Project to help distinguish them from others of the named similarly but configured differently or variations of the same instrument as it suffered dramatic changes during different periods of its history.
