Definition of "corrido"

The Mexican corrido remains essentially true to these Iberian roots in regard to its poetic form and its handling of narrative subjects. It is probable that the term corrido is a shortening of the term romance corrido, meaning a through-sung ballad, as attested in Spanish usage during the sixteenth century (Simmons 1963).
