1533—Seville, Spain
Church records for the Seville Cathedral link the trombone with the contralto part: “On this day the said Lords, called the previous day, submitted [the following] to the Lords Archdeacon De Niebla, Prior and Canon Zambrano, and Prebendary Diego Fernandez, so that they, along with the maestro de capilla, recognize the ability of Francisco de Flandes, chirimia tiple, and so recognizing it, award him the salary they deem appropriate, and also see if Andres de Deça can serve for the contralto, since he is a trombone player [sacabuche], and if it seems to them that he can serve well, that they receive him with the salary that seems appropriate” (Stevenson, La Musica 28-29).
