Brazilian pernambuco is a type of hardwood native to Brazil, known for its rich color and density. It is primarily harvested from the Caesalpinia echinata tree, which can grow up to 15 meters tall. This wood is highly valued for its use in making high-quality musical instruments, particularly violins, cellos, and bows. The wood's unique properties, such as its ability to produce a warm, resonant sound, make it a favorite among musicians and instrument makers. However, due to overharvesting and habitat loss, pernambuco is now considered endangered, leading to strict regulations on its trade and use.
