Flamenco originated in Andalusia, Spain in the late 18th or early 19th century. It involves dancers, a singer, castanets, hand clapping, and footwork performed by dancers in heels. Traditional Flamenco costumes for men include tight black pants, a shirt and vest or jacket with nails in the shoes, while women wear heavy ruffled skirts and shawls. Major Flamenco festivals still take place today in Spain and other parts of the world. Musical instruments used include the guitar, cajon, and palillos for clicking sounds, while palmas involves hand clapping to keep rhythm.
