Flamenco has changed over the years, picking up from Latin American and other influences along the way. The dance starts slowly, and speeds up as the dancer injects more feeling. The moves are many and follow a strict pattern, all artistic in their way.
Modern flamenco dancers still adhere to the artistic, but now inject their own temperament into the dance, which makes for a more fluid and fast performance.
Music for the dance is provided by one or more Flamenco guitars and, very often, words accompany the music. There is a considerable amount of Moorish culture in Spain, and I say this now because the songs are nothing like what is heard across the rest of Western Europe. One can hear the Eastern influence quite clearly.
