The most characteristic Spanish march form is the pasodoble. Spanish marches often have fanfares at the beginning or end of strains that are reminiscent of traditional and popular music. These marches often move back and forth between major and (relative) minor keys, and often show a great variation in tempo during the course of the march reminiscent of a prolonged Viennese rubato. Military marches are an adapted form of the pasodoble, which feature strong percussion and have British and French influences as well, as well as German, Austrian and Italian elements. Typical Spanish marches are "Amparito Roca" by Jaime Teixidor, "Los Voluntarios" by Gerónimo Giménez, and "El Turuta" by Roman de San Jose. Many of these marches are also of patriotic nature.
