What is "seguidilla"

The seguidilla is an old Castilian folksong and dance form in quick triple time. (The dance portion is spelt in the plural, as seguidillas.) The song is generally in the major key and often begins on an off-beat. The name is a diminutive of seguida (from seguir, meaning "to follow").

The seguidilla is a verse form of Spanish in origin. It has seven syllable-counted lines (7,5,7,5,5,7,5), and rhymes the second and fourth, and the fifth and seventh lines (x,A,x,A,B,x,B).
