Andalusian Classical music was developed in Spain in the region and province of that name. It is primarily characterized by three major dance types: the fandango, the malaguena, and the polo. Each dance form is characterized by definitive rhythms and, usually, quick-paced meters. The fandango is thought to be of South American origin and is written in triple time with a continuous increase in speed. The dance itself has a number of sudden stops and is most often accompanied by guitar and castanets. The malagueña is a variety of the fandango from malala and murcia, which came to Mexico by way of Spanish settlers. It is also a gypsy song involving a great deal of improvisation, cadenzas, and guitar accompaniment. The songs contend with amorous subjects and can be played as instrumental pieces as well. The third dance form characterizing the Andalusian classical style is the polo; it is both a folk song and a dance. Of the three, polo tends to be the most moderate; it's in 3/8 time with an emphasis on syncopation and vocal coloraturas, particularly performed over the syllables "aye" and "ole."
