Pasodoble, or paso doble, (literally double-step in Spanish) is a Spanish light music, with a binary rhythm and moderated movement, probably based in typical Spanish dances of the 16th century. During the 18th century it was incorporated to comedies and was adopted as a regulatory step for the Spanish infantry, with a special feature that makes the troops can take the regular step: 120 steps per minute. The music was introduced in bullfights during the 19th century. It is played during the bullfighters' entrance to the ring (paseo) or during the passes (faena) just before the kill. It corresponds to the pasodoble dance (traditional and ballroom).
