The seguidilla (/ˌsɛɡəˈdiː(l)jə, -ɡɪ-, ˌseɪ-/; Spanish: [seɣiˈðiʎa]; plural in both English and Spanish seguidillas; diminutive of seguida, which means "sequence" and is the name of a dance)[1][2][3] is an old Castilian folksong and dance form in quick triple time for two people with many regional variations.[1][2] The music is generally in a major key and often begins on an offbeat.
The term is also used for a Spanish stanza form with four to seven short, partly assonant lines in a characteristic rhythm.[1][2]
