|In many usages in the Spanish language, what is originally an adjective becomes a noun, and the orginal noun forgotten. So it is here; the original phrase was las seguidillas sevillanas … the seguidillas as they are danced in Sevilla. Now it is just las sevillanas.
The seguidillas is one of the original folk dances of Iberia, and goes way back in history. Dance anthropologists say that it is the original source of much of Spanish dance, and we know that it is more than four hundred years old.
Las sevillanas is a social dance and in order for a dance to be accessible to whoever shows up, the rhythmic structure and the choreography have to be stable. This is the case, and if you learn sevillanas in California, and you go to Sevilla and someone asks you to dance the sevillanas you will be able to do it. The senorito sevillano will usually have embellished the choreography to show off how cool, he is, but it will still fit with the academic form. (If it doesn’t, just tell him to get lost.). Thus, sevillanas differs from all flamenco forms which are subject to shortening and lengthening of passages at the discretion of the dancer and the singer.
Sevillanas are danced in the form of four verses, or coplas. There used to be seven or eight, but the last three or four have been forgotten. The rhythmic structure is simple in the extreme, being a six count phrase, and each step in the dance then occupies those six counts. (A musician would say that this was two bars of 3/4 rhythm.) Six of these steps constitutes one section of the copla, the last step involving changing places with the partner. Each of these sections begins with a particular step, the paso sevillana. Three of these sections complete the copla, which terminates in a vuelta (turn) to a sudden stop (parado) at the end.
Here is room 206. They will perform las Sevillanas.
